Exactly, gender isn’t important. You could have done the convenient thing and they/themed the imaginary waiter. Why did you choose to go to the effort of assigning a gender when gender has nothing to do with your point?
Because it doesn’t actually matter what gender I used so I went with she and didn’t put much thought into it. I didn’t think people would be so soft headed as to actually give a shit because it isn’t relevant to the point at all. If I had said “he” nobody would have given a shit, something is wrong with y’all.
