#1 Pet Peeve

I complain a lot about customers, coworkers, the crappy company that I work for, etc. But the thing that irritates me the most about my job is when a customer approaches me and doesn't compose a full sentence. For example, tonight I had a customer walk up to me and he simply said "Playdough." I know it shouldn't bother me as much as it does but when customers do this it just comes off as being incredibly rude. Would it have been that much more work for him to say "could you show me where the Playdough is?".
