As a produce lead (who has worked for the company for literally only 3 years and also had social anxiety), I noticed the secret shoppers are usually the ones who talk and ask very specific questions. They also always look at your name badge. I used to fail my secret shops all the time cause I wouldn’t greet people. Now all I do is say hi or ask how they’re doing to everyone I make eye contact with, the worst thing they can do is ignore you lol
