A couple of years ago, I posted a thread about a crazy call I had from a customer. Can't find that thread, but I had another call like that today, and it made me think of it.
I won't bore you with the technical details of the call, as I doubt anyone really wants to get into a chemistry lesson today, so I'll substitute doughnuts into the conversation so you get an idea of what this was like.
Yog: Hi there, I see you've ordered our Anorexic Diet Meal with extra doughnuts.
Yog: Well, I just wanted to make sure you really want this. The Anorexic Diet Meal [ADM from here on out] is two rice crackers and a glass of water. The doughnuts are fat-stuffed buckets of lard. Are you sure you really want this?
Customer: What's the problem?
Yog: Well. Okay, I guess it's not obvious... let me explain. The ADM is generally for those looking to drastically cut calories. The doughnuts are heavily loaded in calories. You really shouldn't order both together. They don't match.
Customer: Oh. So I can't have both?
Yog: Uh. You can... I mean, there's room on the plate for both, but it just doesn't make sense. May I ask you about your application? What are you trying to accomplish? Are you watching your weight, or do you want tasty treats and damn the consequences? You see, I think one of these two items has been mis-specified, and I'm trying to find out which one, so we can get you what you really need. Because if you are on a medically-restricted diet and you start eating doughnuts, the implications could actually be quite serious.
Customer: You're saying I can't have both?
Yog: No, listen, yes. Yes you can technically have both. It just doesn't make sense. Let me back up. Do you understand why there is a contradiction here?
Customer: Did I order both?
Yog: Yes. Yes you did.
Customer: Oh. Can I get both?
Yog: Fine. Yes. Thank you for your business.
I'm actually feeling a bit nervous about this, because if this guy is flowing Chlorine Trifluoride and has mis-matched his vessel and elastomer material, someone down the line is well and truly f***ed, and liability could potentially flow back to me.
[EDIT] lol, and just now he called back and asked for more details, saying he thought there might be an error. You think? *whew* I think he went back and told somebody smarter than him what was going on and got his butt chewed.
