Whose side are you on?[name that sammich edition -mod edit]

While the employee is right, only one needs to be marked to identify the sandwiches, you dont make a customer feel dumb by arguing the necessity.

Mark the sandwich and move on. If you don't want to deal with dumb people, get a job where you don't deal with the public.

It was later in the evening.

What's no big deal at the beginning of the shift "just mark the subs" by the end of a long shirtty shift of dealing with mean, impatient, rude customers by the end of the day turns into "I will die on this hill"
