Target - Was next in line but when a new register was opened customers behind me got serviced first!
Several times when checking out I have been behind a customer who was having a problem, it could be a price check or opening a charge account etc. A Target employee (this has happened more than once) came around and told the people behind me to go to a newly opened register.
I was left waiting at the first register and saw several of the customers who were behind me leave the store!
When I spoke to the Target representative he said that your policy was to open a register if there were three people in line. Great but that does not mean that the next person in line still needs to wait while the others are taken care of first!
