..and food sales🤔 Of the ones you quote only liquor is something they can sell the others are not related to selling. You also need a license to drive et al..
But Thailand is still freer than most. Kids can't simply set up a lemonade stand outside their houses in many jurisdictions.
This is Thailand I don't think they have licenses to sell. Any Thai is free to open any business they wish. Taxable income starts at 150,000 baht a year. Below that... 🤔
...and for a visa/work permit. Every year photos of the premises, staff, me at a desk, staff at work. et al. and sit for most of the day in area M at Chaengwattana. Just part of the cost of doing business.
Up to you, but you may not get the result you expect.
If you and Will B frequent the same establishment can't you synchronize your visit and annoy each other and not other people. 🤔
