What is the purpose of a greeter? I don't mind being told "Hello welcome to Sam's Club", but waiting to exit because the greeter has to check and mark your receipt is the worst thing about the store.
Most greeters make you wait and have a lousy attitude towards the customer who on average spends more then $50 everytime they visit the store. It's a fire hazard and policy should be changed.
Greeters hate that job position and it shows in there job performance. Let's get some alarms at the entrance and exits and get these greeters some other duties to do.
