I often take a frail handicapped person on my fine dining shops. It really makes the valet and hostess shine or fail miserably.
If the hostess slows pace and points out any possible obstacle, or I overhear them change "server rotation" to bring us to a closer table to the front of the restaurant instead of the "next up" at the backside of the place, I place this in the report. I am keen to see if they do this.
The same goes with the valet. I leave the handicapped placard hanging on the rear view mirror. We may not be driving a Ferrari, but a good valet will NOT place the car in a handicapped space, yet place it in one of the close prime spots they saved for the high end vehicles.
This does not go unnoticed. I did a fine dining shop last night and the valet was parking cars like a Disney park does, and just going up and down the rows to next spot and leaving the front spaces open. They parked the car one space off the handicapped parking as close to the front door as possible.
When we departed, the valet remembered us and ran to the car and had it to the curb of the restaurant in less than a minute! There were other customers who waited in a 5+ line. The valet immediately bumped us.
