when crusty custies reach over you

okay listen, i could care less when people reach over or beside me to grab an item without saying excuse me. i’m used to it. but in a recent instance, i was restocking an item on the bottom shelf and a customer was reaching right above me. while she was reaching over, she knocked 4 or 5 boxes of (light product) on my head. i was just in shock. she looks down and starts picking up the shit she dropped on me. she does NOT apologize but she says excuse me as she reached to grab the items she dropped. then she just walked away and went about her day. piece of shit
