I go in wired with my DVR. I announce the time in just as we reach for the door (6:02:18) and leave the DVR on so that I can count seconds between that time point and the greeting without announcing a time point. As soon as we are seated, I announce the next time point as (03:58), which I know will be 6:03:58. If we had a wait, I paused my DVR until called and announce the call point as just minutes and seconds, then announce the seated time to start timing for the greet time. While waiting for the greet, I record the demographics of the hostess and the name if she had a tag. I have my microphone in my bra and put the DVR in my lap under my napkin so I can easily turn it on or pause it and I just look down, even in a crowded and noisy restaurant, to tell myself the timings. I record the greeting of the server, what was said as the dishes were presented, what was said when the bill was presented, what was said when the credit card slips were brought back and a time point for every service. I may make notes to the DVR during the meal about presentation, especially for what may be in the salad or slaw or other mixed item. I then have the recorder on as we depart to capture any farewells we are given, the time we walk out the door and anything unusual I might forget to mention.
For a 1 hr meal there usually is about 5 minutes of DVR to listen to, and I do so with a timings spreadsheet I have set up that goes through all parts of the meal. The spreadsheet then subtracts delivery time from order time for me, greeted time from seated time, credit card taken from credit card out time, etc. etc. On the spreadsheet I also have a column for descriptions of everyone I interacted with and names and a space to put exact quotes of upsells or suggestions, greetings and farewells. I have a space to do the pre-visit call, including #of rings, exact quote of greeting, name of employee, time and date of call and what they told me. There is also time in/time out, times of table visits for satisfaction/refills etc. and who made them.
It takes generally 10-15 min to manually transfer the information from the DVR to the spreadsheeet, but there is the shop in a nutshell. When I am asked if the appetizer was delivered in 10 minutes or less I can confidently state 'NO' and mention it was delivered in eleven minutes and eighteen seconds. Whenever I can use the direct quotes or exact description, I can just copy and paste into the form.
The timing sheet and timing habits are now automatic to me and I find they work for any casual or fine dining situation. The timing sheet becomes part of my permanent record for the shop along with the scans of receipts and a pdf copy of the report. If something specific is requested for a particular shop, it can easily be added to my blank for that shop.
