It's true that an an MPA's mood may play a big role in her services and of course as with any MPA, it's always YMMV. So you can't go in expecting what the previous person received, be it bad or good. However, on the topic of YMMV, there are various reasons an MPA will take into consideration, be it age, body type, hygiene (which is a big one) and of course race. I'm hoping everyone's hygiene is up to par, and if it is, other than having a moody day, what else could it be considering the differences in service one person received where another received literally the complete opposite? Race? I don't want to play the race card, but just out of curiosity, is her YMMV based on race? With that said, may I ask what race you are and if you received one of those spectacularly reviewed services or the other end of that stick. Might as well throw in age and body type as well so we all know what we're dealing with.
