I would think it would be hard for a quick serve to work more than once and even the first time you could just say, "first serve, I wasn't ready." After that, just walk to the receiving serve position holding your racquet in your off hand or holding one hand up and don't put it down until you are ready to receive.
Luckily like some of you who have already responded I've never faced a quick server, in fact, my peeve is with the opposite type who take forever to complete their service delivery. The worst offender at our club in this regard also foot faults on every single serve making him doubly fun to play against.
Thanks TW for the version reversion and Xenforo FTW!
