I had the EXACT same problem when I was working in an ice cream store in high school and did almost exactly the same thing until the policy changed where each person could break one time for 10 minutes in a 6 hour shift, smoker or not.before i started my business 20 years ago i worked for a comapny where poeple would go out and take cigarrette breaks evey 1/2 hour or so.
they lasted about 10 minutes. they always seemed to do it when it was the busy hour(restaurant).
I dont smoke, and i resented it that these people were not only rewarded for their habit by getting a rest break, but they also dumped the extra workload on us nonsmokers.
so ol' fishguy came up with the "non smoking smoking break"
I would stand there when it was busy, lean against the wall, give a look as if in deep thought, and blow off any calls for help from inside.
i just stood there.
when i was confronted, I explained that i should also get the same rights as a smoker gets. the smokers were really pissed off, the manager was in a corner with this approach(i was an excellent worker), and some of the other non smokers joined me.
the rule was, you needed to lean against the wall, and just stand there,.................BSing was allowed.
my point was made, and the smokers were not allowed to take these breaks until it was not busy. i didnt care if they smoked, but i sure did resent that it made me have to pick up the slack for their habit.
to this day i stil laugh at that situtation.
