I was recently asked by, I think, eBay, to review a product I purchased: a toilet seat. What on earth should I say? That it doesn't have splinters?

Most of the restaurant surveys I'm asked to fill out offer a discount coupon as a reward. Only trouble is that (a) the time frame for using the coupon is absurdly short, say two weeks; and (b) it's never valid if you have any other kind of coupon as well. Make it a real reward, not a phony one you know 99% of people won't be able to use, and I may fill these out.
