they are worth it. when I first moved here I had a guy at Megamart, that when he saw me coming, would follow me all around the store, steer my cart for me, get things off high shelves, hold my baby, and then make them open up a checkout lane so I didn't have to stand in line and then bag and take my stuff to the car. He was of great help as I buy A LOT of stuff (have a big family) was wrestling with a baby and trying to get through the under construction parking lot of megamart. I was sad when he returned to India.
