Today at lunch I asked to be seated in a particular waiter's section, and unlike previous instances where I had made this request (at other restaurants) they didn't say "he's not working today" or "his section is full". (Due to my lack of success I had begun to think that asking for a particular server worked in theory but not in practice).
So today they seated me in his section as per my request and when he came he was delighted and thanked me for asking for him.
Lunch of course went perfectly this time as I figured it would. This waiter had of course waited on me a couple of times in the past and the experience was enjoyable each time. That's why I asked for him.
What made me decide to try again and ask for a particular waiter was that lunch last week was a nightmare of poorly timed food delivery (see one of my other posts) and I didn't want to take a chance again. So I thought why not try making a special request again?
So I guess sometimes it really does work.
