Like I said, I think it is idiotic to go to a foreign country and start intentionally breaking the laws. I obey the rules, not try to circumvent them. I haven't seen the inside of a Thai jail yet and I plan to keep it that way.
I can certainly understand why they bars would be trying to figure out ways they can open, but posting a menu showing a few sandwiches - that seems awfully risky - too risky for me, especially if they are not licensed to sell food. Maybe they'll be able to get away with it, but I don't want to be anywhere near there if they find out the hard way that they can't.
If your idea of a good time is to be in a bar at 4:00am if the law says they are to close by 9:00pm, enjoy it.
Besides, at my age I don't want to be anywhere at 4:00am other than at home sound asleep . . .
