Rajesh's Driver Plate Match

Two people pass one phone back and forth guessing which lorry driver eats what, and the guessing quietly builds a book of every regular who ever stopped.

Who this is for

Rajesh runs a dhaba on NH-48 outside Behror. Twelve charpoys, four tables, a tandoor that stays warm from five in the morning. Around forty lorries a night, and maybe sixty drivers who have stopped more than three times. The dead hour is between two and four, when the last truck has pulled out and the cook's son is wiping down the counter with nothing left to do.

How the job is done today

Nothing is written down. Rajesh simply knows. The Kandla driver with the blue muffler takes dal fry and four tandoori roti, no salad, green chilli on the side. There is one notebook, but it is only for udhaar, with lorry numbers and amounts and dates, and half the pages stuck together with oil. When Rajesh went to a wedding in Alwar for four days, the cook's son had to ask every driver what they wanted, like they were strangers who had never eaten here. The drivers noticed, and said so.

The screens, in order

1. Two names — Sets down who is playing tonight and keeps the score running between them until one of them stops.
2. The lorry number — Puts one lorry number on the screen so whoever is holding the phone can say what that driver always orders.
3. Pass it over — A blank cover screen so the answer stays hidden while the phone crosses the table to the other person.
4. What they really eat — Shows the stored order, awards the point if the guess matched, and lets either player fix the record on the spot if the driver has changed.
5. Tonight's score — Ends the round with who won and by how much, so there is a reason to play again tomorrow.
6. The driver book — Lets anyone look up a driver by lorry number, name or town, even one who last stopped here three years ago.

What it keeps track of

• Drivers — lorry number, the name they go by, their town, the first night they stopped here, anything you would recognise them by
• The usual — which driver, what they always order, how they like it made, what they never touch, when this was last corrected
• Visits — which driver, which night, what they actually ate that time
• Rounds played — who was playing, which lorry number came up, who guessed, right or wrong, the date

The one decision that matters

When a guess is marked wrong, who is right, the phone or the person. One way, the stored order is final, the guesser loses the point and the round moves on. The other way, either player can tap and say no, he shifted to plain roti after his stomach trouble, and the record changes there and then. Go the second way. The whole worth of this thing after two years is that the book is true, and the only moment anyone will ever bother to correct it is the moment they are annoyed at losing a point. A game where the phone cannot be argued with is a game that slowly fills up with wrong answers nobody trusts.

What to leave out of the first version

Leave out money entirely. No udhaar, no bill totals, no who owes what. The moment the app can tell Rajesh that a driver still owes four hundred rupees, it stops being the thing you open at two in the morning for fun and becomes another book to keep. Let the oily notebook keep the accounts. This one holds only food and names.

How you would know it worked

A driver walks in after eleven months away, and the cook's son reads the lorry number, checks the phone, and calls the order to the kitchen before the driver has sat down. The driver laughs and asks how he was remembered.

Build it

Paste this in and let it run.

I run a dhaba on the Behror highway and I know what about sixty of my regular lorry drivers eat without asking them, and my nephew wants to learn it. Make me a small game for one phone that we pass between us at night. It shows a lorry number, whoever is holding the phone says what that driver always orders, then a blank screen so I can hand it over without the other person seeing, then it shows what the driver actually eats and gives a point if it matched. If a driver has changed his order, either of us should be able to correct it right there so the answer is right next time. Keep every driver, his lorry number, his town and his usual order in a list I can search by lorry number even after two years. No money, no bills, only the food and the guessing.
