I once had to get some things printed out, and when I arrived at Office Depot, one employee had helped me out despite doing many other things. I got my copies rather quickly, and that same employee proceeded with helping the other clients present.
The in-charge then finally appeared to assist the other clients, but this is only after that person showed he was upset that his order still wasn't prepared. The same in-charge then told that client that he wasn't though since the other employee was still assisting me.
Basically, this in-charge plays favorites and assists whoever she wants to assist. To make matters worse, the in-charge sent home that one employee who was handling all of our transactions as she just stood there. That's simply not right.
