I can. I do high school senior photography and I asked the kids last year where they worked, and how much they made doing it. Oddly, that doesn't seem rude to ask 17 year olds.

The ones working at Walmart absolutely made $17 an hour (then). It's Walmart. They aren't playing games with stuff like that. I'm sure they're mostly doing under 32 hours a week where possible with their employees as usual.
