If there’s no price menu they can charge whatever they want at the end. I’d rather know beforehand, especially if it’s not just one beer and I’m there for awhile.
Most places will put out the chit for each drink, but it’s after I order.
They don’t all have the same 4 beers. Some places have tiger, others don’t, one may have corona or beer Lao, others don’t.
With no menu I am drinking Leo instead of the beer Lao just because it’s an easy understood order. I could go look in the freezer myself which I sometimes do. You get the idea.
