Hey, been lurking a bit since I started as a WG recently and thought I'd add my two cents.
I think when I joined I did take it to mean "enjoys" in the literal sense of the word, naive and all. That said it's pretty obvious that anything you indicate you like, you might be asked for. So I only put down things I actually enjoy and would do with punters. I did wonder if being truthful would affect the response to my profile but figured it would result in the kind of people I would want to see.
I do think changing it to "offers" would be more appropriate, but guess it doesn't sound as appealing and it probably wouldn't prevent those people ticking all the options just to broaden their potential customer base.
Someone mentioned the "at discretion" options sometimes cause issues - I think we should have to elaborate on what and why that discretion is if we've decided to tick it rather than leave it off. Could give you a bit more of a realistic idea of whether you could actually get the service...
