I have seen a tow truck driver in a uniform store trying to buy hats and t-shirts that said "POLICE" on them. He was on the phone with someone else asking them what sizes they wanted also.

When I stepped up to the counter and made my purchase I thanked them for being responsible about who they sold to. His response was "they try it all the time but will not give up".
