Likely by another of the waitstaff. Busboy perhaps?
I worked as a busboy age 14-16 at a busy place along interstate.
More than a few times, the waitress would ask me if I saw any tips. Pretty much accusing me of stealing in a nice way. I never stole a nickel. Even had one check the tub after picking up the dirty dishes, to make sure I did not wipe up the change! LOL
Some could not accept the fact, they either did poor service, or had a tight wad customer.
