That tops mine.
The local Meijer has a Starbucks-like coffee store inside and I saw someone wandering around the store with a mask, dangling below the chin, gloves, and drinking one of those coffee-shake mocha drinks. Said individual adjusted the straw by holding it at the top with the aforementioned gloves.
Besides that, and maybe it's just me, but if you have time to slurp down one of those drinks, you're browsing, not essential-shopping...
