I have been accused of being a PIZZA HUT delivery man.... I have the hat, the empty box and the sticker for the side of my car... works for me.... and you won't get arrested for impersonating a PIZZA man... even in MN.
I also have a full uniform for a UPS (United Parcel Service) delivery man... but that is because I am a retired UPS employee.... that also works on occasion... also not an arrestable offense...
"Pardon me sir... I have a special delivery for "******"... he must sign... I think it is a check!!"... works for me...
... of course... you can also dress like this....

... or this... and that hat should get you some recognition... especially in certain cities in Michigan... ?!! or is it MN...
