This is one of my BIG pet peeves and I have dealt with it quite often. I think it shows a COMPLETE lack of respect of the person's time and a COMPLETE lack of knowledge or care that a presentation doesn't "just happen" all on it's own, but rather it takes time, effort, and appropriate scheduling. Not much pisses me off more than people who see some very small part of whatever it is that we might do, such as a presentation, and ASSUME that the time spent on what they can actually see is all that's required of us. This happened a lot when I was a real estate appraiser. Loan officers would generally have ALL of their package ready and would have taken a MINIMUM of a MONTH to have surveys done, credit reports, home inspections, repairs made, yards sodded, etc.........and then call me at NOON on Christmas Eve and INSIST that I "run out there" and get them an appraisal so this lovely famblee can close their loan the day after Christmas. They act as if the 45 minutes I spend at the house is all it takes to hand them the final 25+ page report, complete with pictures of the subject house and 3-5 other houses in the area as well. ASSHOLES.
I have told those same fuckers over and over and over and over, that even if it was all I had to do that day, AND there were no snags, no problems, no traffic, etc.......it would take me a MINIMUM of eight hours to prepare it which would put me working straight through until late at night on Christmas Eve IF I skipped dinner and only took one bathroom break, or having to come in on Christmas day and finish it up in order to meet their deadline. While I am busting my ass, missing holiday time off, and working alone in a dark desolate downtown building, they will be sipping eggnog, setting out Santa Claus, and gnawing on a turkey leg. Of course I never succumbed to their demands, but the very fact that they asked me to do this pissed me off royally.
People who spring "emergencies" on others who provide a service to them and demand immediate satisfaction without any consideration or concept of how time consuming or inconvenient their request might be are SELFISH BASTARDS. They are deserving of no reponse beyond, "No, I can not meet your needs within that timeframe. Like I have said many times in the beginning and in the past, I need a minimum of a week's advance notice and that is not going to change. It's really a waste of your time for you to continue to ask me to do something within a time frame which is impossible for me to meet, perhaps you can find someone else who can better meet your demands", which is pretty much what I said to the repeat offenders. Oddly, they generally start acting right and following MY rules after I lay it out for them in that curt manner. They find out pretty fast that professionals who need NO (or little) notice to produce or perform generally are not very good at what they do, hence the extra time to accept jobs without notice.
I HATE THESE PEOPLE and avoid them whenever possible.
