Stopping by three different Costco's in the greater Atlanta, GA area I've noticed the lines to leave the store after purchasing goods are intolerable. Costco is insulting the customers by expecting them to wait for a employee to "check" the receipt.
Profiling all customers as shoplifters is inexcusable.
I just stood in line to purchase my goods and now I need to stand in another to "Prove" I just purchased the same goods not 10 minutes prior? Absolutely not. I've restored to just bypassing the exit line, staring the Costco employee/bouncer down. If they say anything I reply with a curt "No thank you" and keep walking.
Retail employees are not Law Enforcement. And walking by them is not illegal. I do not answer to retail employees.
Also the Inventory assets and protection system should suffice.
Respond if an alarm is triggered THEN check a suspicious Customer. Do not assume we are all thieves.
