I would agree with all of the comments. I have shopped for them and have found that their narratives are very detailed.. nothing quick at all in the level of detail that is duplicative of the questions. Their pay is very low, the shops are limited and after completing three shops, I'm not sure it's worth the effort.
As an example, I recieved a clarification email around a minor issue that I would have no way of explaining. When you have detailed that the site is busy, there were numerous tables waiting for orders, and staff were all actively engaged in providing service it's hard to provide any other explanation as to a delay in the order. If you are not in the kitchen, how would you know? I recieved a second stern email stating the shop was overdue within an hour of the clarification email. I understand the need for a quick turn around but it's not realistic to be stationed at a computer( no edits can be made via any mobile device) for an entire day after a shop. It would be easier to respond if this was not a restriction.
The pay is very low, the reports are repetitive and the narrative is lengthy. I actually joined the site to help out the recruitor but after trying them out with three shops, I think I will not do any additional evaulations for them.
