One more stop before home
Food carts, bright lights and the comfortable untidiness of eating outside.

The plan to go home can survive several small revisions. Someone notices a food cart. Someone else says they could eat. A few minutes later, the group is standing under a bright light, reading a short menu and making room for the next person in the queue.
Eating outside late in the evening has its own practical rhythm. You hold a drink in one hand, find somewhere for a napkin and negotiate a hot first bite without the usual table. Conversation comes in fragments between orders being called.
Make room for the pause
There is little point treating a stop like this as an obstacle between you and the end of the night. Once you have joined the queue, you are there. Put away the route home for a few minutes and look at the small operation around the cart: the repeated movements, the handover of food and the brief conversations with regular customers.

A photograph can hold some of that activity without explaining all of it. Keep a little of the surrounding darkness so the light has a place to fall. Hands, steam and half-visible faces may tell the story better than a carefully isolated plate.
The people working are busy. Ask before making close portraits, leave the counter clear and be ready to put the camera away when your order arrives. The food is part of the evening too.
By the time everyone has finished, the conversation will probably have moved on from whatever brought you out. Fold the wrappers, find a bin and check the journey home again. An unplanned meal can make a natural ending, even when it was supposed to be one more stop on the way.
