Hi Lucky,
Sorry you are upset, but wanted to comment that everything you posted seems reasonable from Coyle's perspective. If you read their examples, they do want an exact time everything happens.
Your report is DUE in full completion at a certain time. If you sent it in, but missed all those timings, then in their mind, you didn't submit it. You need to get back to their editors ASAP (and you will be dinged a point or two that their editors had to come back with questions). Try to plan to be present and able to respond to emails for about 24 hours after you submit a report. Doesn't mean you have to not make plans, but be able to send a quick email. As you improve, you will get to a point where you don't have any follow up questions from the editors, so won't have to worry it.
As far as the editors sending you an email with things that were mentioned already in your report, that is strange. Either that editor was new and made a mistake OR your writing did not follow the structure in the example and the editor found it hard to follow, so decided it was easier to re-email.
As far as remembering the times, it is hard. I keep a digital list on my smartphone of all the time stamps I need (about 10+ in a given restaurant). I note the time I am entering before I enter, in my phone. Then I rely on my memory to remember the next bunch of times. Then, I go to the bathroom about halfway through the shop (to evaluate the bathroom), but also take a moment in the privacy of the stall to empty my mind of all the times I was remembering by writing them in my phone. Then, I complete the second half of my shop, remembering all the times, and the second I get in the car I furiously take notes. If I am having trouble remembering a time or two, I assign my husband one or two to remember. I am happy to help with any other tips and tricks!
