Home Depot I guess...
God this woman deserved a quick visit of the hammers' aisle, complete with a demonstration, first on her incontinent offspring, then on the rest of the family, and of course, service with a smile...
There are times where I think store/hotel employees should have the right to exert aggravated physical punishment on the retards who call themselves customers of patrons...
Now another anecdote I remember was rather harmless, I wasn't a clerk in this video game shop, but I felt for both the poor customer and the poor clerk.
I was buying some owned 360 games the other day, and discussing PS2 and Xbox with this clerk when an old lady, visibly a bit lost enters and tries to scan the place, to find some lighthouse in this foreign sea of logos and boxes and stuff she could not make out for the life of hers. Then we both ask her "Need anything ma'am ?" (for ease of writing, assume the clerk and I are the same person in the dialog).
She very nicely replies "Why yes please, can you tell me what an xbox is and how much it costs ? It's some kind of game I believe."
"Well, uuuhhh... it's a console ma'am, which means it's made to play games, but it's not really a game in itself..."
"Oh uh... you know I don't really get all these, it's my grandson/daughter (forgot) who said (s)he wants one, so I'm asking and all."
"Mh... how old is (s)he ? You see, the cheapest model of xbox (we conclude it's a 360 she's looking for) is 200 euros and there are no games included (well of course there are XBA demos, but I doubt it counts for kids)."
"Well (s)he is 4, turning 5. It's expensive... and there are no games with it ? I don't get it."
We look at each other with the clerk, and we are both puzzled... So we walk her to the 360 games and we take one (it was Kameo or Viva Piñata, something PG 3+ for sure) we put in the 360 on display. Basically we explain her how, like with a VCR or DVD, you need to put the disc/tape in the machine to have something to do.
"Ooooh I get it, well it's nice and all, but it costs a lot, I don't know..."
"Ma'am, in all earnest, don't buy one, most of the games are not for kids."
"Oh, but what should I get for his(her) birthday then ? (S)He wanted an xbox."
"... Well if the kid wants video games, get him(her) a gameboy adance and super mario, nintendo consoles have literaly tons of games aimed at kids and all."
"Oh, and how much would it cost ?"
"Not much, buy it second-hand, you can have a console and a handful of games for half the price of an xbox, and it would be more suited for a 5yo -yet in my opinion, you'd better get her other toys or a kid's book or something, she'll have plenty of time to play video games."
"Oh, I see, so the gameboy's the name, right ? and like the xbox, you need games on top of the device ?"
"Exactly, but now it's cheaper, moreso used"
"Oh, ok, then I'll have a chat with my daughter and then we'll see, maybe I'll come back"
"Please do"
Basically this time the customer was more confused than wrong, but we felt bad for this grandma, we pictured the kid as a spoiled brat whining for stuff seen in TV ads, and the mum using her mother as a nanny and a present dispenser, maybe we have been harsh, but it was how it appeared to us from how confused she sounded, just entering a video game shop.
