He was a man. Men think they know everything. I've had issues several times when I've had to use the carts at Walmart. I had one guy tell me that the carts are for people who are disabled, not people that are fat because they are too lazy to walk (I can't walk without support, and not very far). He told me he needed it and I said he could ask the employee to help or he could wait till I was done. He said "but I'm a veteran," and I said "and...? I'm a single mother. Have a good day, sir," and rode off.
