You can't eat melon seeds in the hotel, but guests insist on eating them. What should I do?

The customer is God! If you can't make sense, you can only make way. Most people are very reasonable and can be solved under explanation. Don't listen, either your expression makes others uncomfortable or you are looking for trouble. . . . But it doesn't matter, you can despise him, eat some junk melon seeds, buy the melon seeds of fat farmers if you can, and pretend to be B!
