Simple rules
1 if your allocated space is 8×8 you MUST nudge to expand, at least 20×20, don’t worry about other vendors back mouthing you, they are just envy

2 try to be nice to people but always make mistakes when you talk to them, like the name, or if they have no kids you wish them well, or never married and

3 try to get always more money from customers, and always mention that your weekend was amazing, but don’t forget it the week after

Awesome as people are getting clueless of what they think and say, for example I was listening the end of some conversation between two locals here, the coat white meringue hairdo was explaining to the other how good god was to him for he just found 2 $5 bills on the floor. That means god was very bad to the other person who lost the money
