Sometimes the Coyle surveys ask questions that conflict with the guidelines. For example, the survey asks "were wine glasses kept topped up" while the guidelines specifically say not to order a bottle of wine (in fact, they say you can only order a single glass of wine, which is pretty hard to have topped up, unless by magic).
I find this annoying, so in the comments to a 'no' response, I specify that the 'no' is due to the guidelines, not any failure by the Server. And yet I was apparently faulted for citing the guidelines on a recent grading. So it's discouraging that Coyle graders relish pointing out YOUR faults, but are very defensive of Coyle's OWN faults in constructing a survey which penalizes Servers due to bad question design/conflicting design.
But for all their faults, Coyle seems to have the only decent fine dining shops in South Florida - I joined, then quit several of the 'top 15' because they had none, though there MUST be others.
