I was recently at Zehrs on Malden Rd and was having the worst luck with self checkout. Half my items had to be manually inputted, scale wasn't registering items etc. The associate who helped me out was very nice and helpful, and I owe her a lifetime of gratitude for finding my wallet (it was that kind of day for me). All of my ID and even the $20 cash I had just taken out were there and accounted for when I came back for it the next morning. Thank you for turning what could have been an AWFUL experience into a happy one.
