Re: Old joke
Some people are just clueless.
When I signed up with Orange France, I asked if my phone's internet would support ssh and sftp among other weird stuff. The girl I spoke to said "it is a phone, it has a web browser" (I guess failing to understand how email arrives). As it turns out, that stuff does work.
When I renewed my phone, the new contract was the same as the old except Deezer was no longer a freebie. I queried getting Deezer, and Orange's own POS machine said that Deezer was incompatible with my phone (Xperia Mini Pro). Oh well. Went home, turned on the phone, saw the Deezer app, and signed in and used the service to the remaining days of my previous contract.
Obviously it might suck to be somebody feeling hoodwinked by a salesbod, but the fact is... many of them are either stupid or simply don't know. This doesn't make it right, but there's a difference between being malicious and being stupid.
Here's my favourite anecdote. "PC World" in Guildford. Circa Y2K. I was looking for a smallish (~0.5Gb) harddisc for my Acorn RiscPC. I asked the guy at the counter because all the stuff on display was ~2Gb and I didn't need anything that large. The response was astonishing. I was told, by an official uniformed salesperson, that if I needed to add an additional harddisc to my Amiga, to buy one of the original Creative Soundblaster cards because it has an IDE port on it. I thanked the guy and left.
Debugging: Let's see. First, he means SoundBlaster Pro, not the original. Second, it is a proprietory interface of some sort, not IDE. Third, the Amiga doesn't have an ISA bus (without some sort of Zorro-to-ISA hack). Fourthly, Acorn and Amiga are very definitely not the same thing. Finally: I asked if there was a smaller size harddisc, a question never answered. Hmmm... Really, five glaring errors in one short discussion. I wonder if he had to go on a course to learn how to be that stupid (remember, he is selling computer bits, and he gave an authorative (if totally moronic) response). I'd have been tempted to shout "FAIL!" and walk out, only we didn't have that word back then.
