First off this store did have all that I needed. Recommend this store: Yes for items available, No for Checking Out / Service.
When Checking Out, I got in line. (Please note: In my basket I had things that kind of 'overflowed' the cart. Not terrific for maneuvering.) After a moment or two in one line, a cashier who had been chatting away with a colleague, said "I can help you over here" in another line. It was a challenge to back out and get the cart over to the other cash register. When I got over to the other cash register, the cashier was busy doing something, and so I started to unload my purchases. Halfway through unloading my cart, the cashier said that the items could be scanned with a hand scanner. So I reloaded my purchases and then my items were scanned. After scanning my items, I was asked for a 'PO' or 'Job Name', or something like that. (I am just a guy off the street who wanted some things.)
It seemed that almost everything to block me leaving with my purchases was done. Instead of observing people, and asking if I was ready, as I approached the check out locations, the cashier just talked with a coworker. Then instead of observing that I was unloading my cart, something else took the cashier's attention.
When the cashier asked for a PO number or Job Name, rather than taking time to explain what those are, it should have been obvious that I had no clue, and should have moved on. (Making me feel stupid in the process.) The asking of a PO number or Job Name, I feel, is lame without an 'opt out'.
So I would say, there needs to be attention to the customer.
