Dollar Tree — Local services in Rockwall

So I've been to this location many times. It used to be very nice and my favorite dollar tree to visit, but I'll likely not be back after today's visit. The store was trashed out and disgusting, a complete turn around to what it looks like normally. When I first got in line to check out there was only one register open. Shortly after a second one opened and the line split. I went to the new register. The cashier for the new line checked out two people and after being called over the loudspeaker proceeded to tell the person and front of me and myself she couldn't check us out and we would have to go back to the other line which was now longer than when we left it instead of checking us out. The person in front of me only had two items and I only had 5 or 6. There was no one else in line behind us either. So we would have been rather quick. Thankfully another customer witnessed this and allowed us to go ahead of her. Shortly after I finished checking out the other cashier came back out and rudely spouted across the store that if we were in here line previously we could come back. I've worked in customer service and retail for years and would never have treated customers so poorly, without reason. This is unacceptable behaviour and to be quite frank this individual should be fired for her piss poor behavior towards customers who did nothing...

Was paying at checkout and this old a$$ lady named Ruth was questioning me after question all because I had a shirt on that said , "I'm not lazy I just enjoy doing nothing" just because of that she started to ask where I worked and if I did anything, she even said he'll, I could give you a job right now if you want, then she went on with how old I was I said, 20 she was like you should be ashamed and that I should be studying in college! Like hello, we can't all afford an education..then she had nerve to ask where I would get the money I was paying my things for! I just gave her my money just so she could hurry the hell up..so I could leave. She's lucky nobody has put her in her place yet cause that's what she needs! Please try avoiding her if you don't wish these kinds of insults upon yourself or...

Just left this store without my purchase. I stood in line at register 4 (light was on). The presumed manager told me that the cashier would be closing and to move to the next lane. I did so. A couple moved to register 4 next and they proceeded to check out the customer after telling me to move. I stated to the presumed manager that this was unfair because she just told me to move. She said that she was sorry but the couple was right there. I was being forced to remain in the lane with the longer line. I decided to leave the store without my purchase. Not sure if it was racial (I am black; the couple was white) or just bad service. I will...
