Cynb, I enjoy their grocery shops. Once you have done the same stores often enough, you will know the employee's well enough to remember their names and descriptions over time. I know that's my case at least. You need names but only 2 descriptions as long as the others are wearing name tags. You have to spend 30 mins in the store and sometimes that seems like a long time, but otherwise I find the shops easy now. I have a handful of these in a few weeks coming up just in time to get groceries for Christmas dinner.
As to their penalties, yep you need to get your shops turned in by midnight. Even a minute after and you take a chance of getting a penalty assessed. They have gotten much tougher in that regard this year.
