There are only two registers open with 15 people in line between them. WHY? Is this indicative of Dollar Tree’s customer service?? Does the average cost of goods determine level of level of service?

They have both registers open check people out. Some people didn't have that many things.

I was there last night. They opened all the registers because there was a lot of customers in line. The cashier's have to do both stocking shelves and also work the cash register

Sounds like that's a question for Dollar Tree.
