My point is that it's bad business practice because it results in lower revenues and less absolute profit because the restaurant requires people to carry enough cash from a rip-off Thai ATM to cover their group's bill and be aware of that total count while they are ordering another round of drinks for the table or deciding not to. Less absolute profit from (a) lower overall bills; and (b) fewer overall customer visits because I choose to eat elsewhere in the future. Anyway, we'll probably never agree on this which is fine. We will eat pizza in different restaurants in Samui.
