Dollar Tree review: complaint

I just got done shopping at the gainsville location and as we were heading to the cashier to check out I walked up to a woman croutched down touching her face with her eyes closed and mouth hanging open. She looked obviously high out of her mind. I backed away to which she had no clue at all that I was even there and almost just left everything there and walked out but my husband insisted on checking out. I let him unload our cart as I ran to the rest room. When I came back she was still checking our couple of items out. She couldn't focus long enough to get anything scanned the first couple of times she tried and kept stopping and her arms would drop and she would start crouching again. My husband said that when ever she got close to the register he could smell alchohol from her . Only one other person was in the store and was only watching her. Something needs to be done about this or next time I'll be calling the police. Her name is Michelle, we checked out at 19:41
