59. Need two people to pull this off. Fill up a shopping carts with random stuff, maybe some diet pills, tons of vitamins, laxatives, adult diapers, potato chips, candy, beer, toilet seat, paint, etc. Find a potential and unexpecting victim. One switches out the wagon on them while they are busy scanning the shelves and quickly ditches their wagon just around the corner while the other person shops in the aisle to catch the reaction of the lost wagon. Take turns pulling off the gag so each of you get a good laugh.
60. Grab a clipboard, paper and pen from the office/school supply office, some reading glasses and a baseball cap. Approach customers in the store and tell them you are doing a survey on customer satisfication and would they like to take your survey. Ask their opinion on the quality of merchandise, how they would rate the associates that work there, and are they happy with their shopping experience, and if they have ever had a bad experience in the store they would like to share.
