A Rare Aggravation

Generally the little store owned by the Three Z's is a peaceful and lovely place to work. Nice customers, interesting people, and rarely is anyone disgruntled. It is not all that unusual to have some well, off-beat folks visit. Mostly they are sweet and nice, but every so often the more off-the-wall oddball visits. While working at the Three Z's shop yesterday...

Random Dude: That is going to kill you.
Me: *Looking for imminent death and seeing none* What?
Random Dude: The Diet Coke. It's going to kill you.
Me: Uh, thanks. Yeah, it's not good for me. *Looks skeptically at the tiny 12 oz bottle of DC*
Random Dude: Yeah, like it is going to destroy your health.
Me: Well, it's just about my last vice, so I sort of cling to having one a day still.
Random Dude: It's not good for you. I bet if you stop drinking it you will feel so much better. Like, when people ask me for health advice I always say that they should stop drinking Diet Coke. You should drink something else instead. Like coffee. Drink coffee all day long. Or regular Coke. Or (lists 400 beverages). Anything is better than Diet Coke. It's going to kill you.
Me: Thanks.
Random Dude: Lectures about the perils of Diet Coke....again.
Me: Thanks. *thinking, SHUT UP SHUT UP SHUT UP SHUTUPSHUTUPSHUTUPOHMYGODSHUTUP!!!!!*

Random, preachy, annoying, irrelevant and unsolicited advice is perhaps my least favorite thing. Ever.
