Secondly, and most importantly, you must have a decent booth, which I will emphasize once.
The booth is very important. All suppliers have their own default or occupied booths. You don't leave early, but this seat is yours. So you need to step on the spot and see where you can set it. By the way, you can find out if there is an urban management here. If yes, do you have to pay the booth fee or are you not allowed to set up a booth here? Want to know more about urban management, how to run?
When the problem of the booth is solved, you can prepare your snack car, purchase ingredients and so on. ...
Everything is ready, and then on the road ... I wish you success!
