I was called my sister's Mother once
Know what you mean about how poorly those speakers at drive throughs
work most of the time. I can't always tell either if it's a male or female
taking my order. But he didn't have to be rude to you.
My sister (9 yrs younger then me) and I were in a ladies upscale clothing
store one time and a sales female (about 25 yrs old or so) came up to us
and said directly to my sister "Are you and your mother looking for something
in particular today?" After I shot her a dirty look, I turned and walked out
of the store. I could hear my sister telling her that that was her sister not
her mother. If that gal had had one ounce of brains she would have said something like "What can I help you ladies find today?" Needless to say I
never shopped in that store again.
