I recently was performing a gas station shop and after noticing a person taking a picture of pumps they went inside to get the employee to authorize a form. I am pretty certain they were performing an audit. I waited in line and made my purchase, but after asking for a reciept the other (im assuming shopper) looked at me and smiled. I have never seen another shopper while shopping and I am curious if anyone else has. I dont know if I should tell the msc I saw the other shopper while doing a shop. I know our identities are to be kept top secret. Also why evaluate customer service and perform an audit from the same day? Anyone else have stories of something like this happening?
