Wow, they got kicked out for some dirty words and physical skinship without a single warning beforehand? What a shitty place, they sure are strict and arrogant for a generic diner.
@Acolytus It's Japan, so public skinship is looked down down upon. It's only something you should do in private. But I guess this is the only manga that implements this that I know of since I've seen so many harem protagonists or typical class leader with a harem, get away with girls literally hanging off them.
