I did once complain about a waitress, that was back in the 1960s and I was in my early 20s. I used to lunch in a little cafe, all squashy seating and low coffee tables, quite tightly packed.
One of the waitresses wore a skirt so short that when she bent to clear a table, as she wasn't wearing tights, the skirt went right up and you face was almost in her bum crack. It wasn't very pleasant.
I could have said nothing and gone elsewhere, but the food was good and reasonable, so I just had a quiet word with the manager and drew her attention to the problem, which she understood immediately.
After that the waitress wore trousers.
