There's a guy at my gym who constantly (literally--without ever stopping) clears his throat and hums. He sounds like Beavis and Butthead (the '90s cartoon, whose main characters constantly made weird and annoying noises).
For example, I'll be sitting there lifting weights, and he'll come right next to me, clearing his throat, saying, "uhh, uhh, hmmmmmmmmm, uhhh, uhhh, ummmmmmm", and clearing his throat, all without stopping. He's literally never silent.
I have nothing against him- he must have a medical issue, and he's not targeting me with his noises.
OK to say to him, "May I offer you a cough drop" or something? I'd just like to help him out.
