yes be blunt but in a polite manner to avoid him making a complaint, tell him you don't smoke weed nor have you ever and that you would appreciate him not accusing you of being on drugs because it makes you feel uncomfortable/insulted and request for him to not lean on your pedestal thing and gazing at you as it make you feel unease in your own work environment.

I think you should just be blunt back like you said. Don't be rude or nice just if he asks that again just say 'no' don't be rude bc he's a customer but make it ovious you want him to stop

Talk to your manager .. Tell him there is this guy who makes me feel uncomfortable...he will prolly get someone else to serve him when he comes to your restaurant.

Could you get someone else to wait on him? That way you avoid the situation entirely.

I work at a restaurant, and this same guy that comes in EVERYDAY always asks me if I am high, which I am clearly not, I have never been high in my life. The first few times I just kind of joked back but said no...but he is beginning to be very blunt and rude to me. (he is the kind of guy (older) that jokes around with people) but it's coming to the point where he is making me uncomfortable, and there are other people in the restaurant. I'm a hostess and he leans on my pedestal thing and will just stare at me-(Like what do I do-I have nothing to say to him so ill kinda turn away??) then asks me (if I'm high). and he makes me feel uncomfortable so I probably look super awkward. Should I just be straight up blunt back to him? Or what should I do? I feel very insulted.
