It's been a while, but... I did enjoy my work, and left the industry for other reasons but.............. i did get annoyed when clients did not listen to me on the phone as I gave them the final directions to my place. They never listened !
I got annoyed when disabled guys did not inform me they were disabled because of the extra time factor.
I got annoyed when guys overran the time and did not take hints asking for a cup of tea etc etc
I got annoyed when they showered and still left skid marks on the bed/sofa
I got annoyed when they tried to do bareback even though they knew it was never going to happen
I got very annoyed when guys pushed boundaries about where they could cum. I didn't like it in my hair. It very often ended up there.
I liked regular clients because they felt safe. They knew where they were coming, and I knew they would pay me, but every so often one would substitute £20 notes for tens, my fault entirely for never counting it, and then later asking to come back and denying they short changed me !!! Very annoying.
I also got annoyed when regulars assumed they had priorities with time, and also called me when I was unavailable expecting me to be there at the drop of a hat but that was probably my fault anyway for not being firm enough.
Having said that these were minor annoyances and the job in itself was a joy mostly
