Yeah depending on the day i just might get pissed and ask for a manager. Most of the time they tell me " i can only do it just this once". Whats funny is there is not age restriction on model kits, spray paint and blades yes but not on kits.
I usually go to Hobby Lobby and they almost always give me a hard time about doing it. Michaels hasn't thrown a fit as of yet. I'll give them time, I'm sure they will.
