Adding to the above that annoy me too.
Grocery stores (not sure if it's Illinois, or local suburb/county) that hire cashiers under 21 year, who are unable to ring up adult beverages. You have to wait while they get on the phone to page someone to come over to just move the bottle across the scanner. Now, I look for the older cashiers and go in their line, unless I see a cashier who is a hottie.
And, related to the above, (again not sure if it's Illinois, or local suburb/county), but annoyed when all of a sudden, each and every person, regardless of age, is asked for ID when buying an adult beverage. Then I have to shuffle through all the cards in my wallet to find the driver's license. I'm over 60, and while waiting for my groceries to be bagged, the women behind me, who appeared to be over 70, was asked for an ID. One day I said I didn't have it. They still sold it to me. The worst was when Target wanted to scan my drivers license. I said I no longer wanted to buy the bottle of wine. Haven't shopped at a Target for years.
