Got glue

My son decided that he needs new work shoes because one developed a major problem. I had to drive to Home Depot to get some glue. They had glues for everything. It took me about half an hour to read instructions on packages (forgot the glasses again). Finally I found one that was waterproof, flexible after drying and could bond leather and rubber. I went to pay for it. There were no human cashiers, except for contractor checkout. I had no choice but to use self checkout. Since I never carry cash, I pulled my check card and scanned the glue. The display started blinking and emitting beeping sound. It stopped doing it shortly. The guy who was overlooking the operation of the checkouts said that the alarm was set off because the item needed ID check. He needed to verify that I am old enough to buy glue. It was a surprise, I did not know that kids are still sniffing the glue.
