I've done quite a few "shops" for Grassroots in the past, it's fine and dandy if it just means going somewhere you would normally go to do something you need to do anyway but when they start asking you to open bank accounts and things it gets a bit tedious.
A lot of the time it depends on how much you value your time, is £20 enough of a reward for sitting in a travel agents for an hour and a half telling lies about booking a family holiday to Disneyland?
Originally I signed up just for the mystery element, the idea of being a spy appealed, sadly it's no James Bond role, it's pretty boring and you have to be very quick to accept the jobs when they come up.
I don't bother with it much any more, the only people asking for visits were banks and mobile phone shops and I hate going to those at the best of times.
It's the local Grassroots competition! Get away from my Halifax visits
