Love the picture in the OP with the sullen photographer in the background.
1) My experiences with photographers bar a few are poor. I can be incredibly caustic when the mood strikes me and I really managed to offend one photographer, who spent the first hour or so of the evening reception complaining to me about just about everything. I was responsible for all of his woes apparently, including the fact the 'house lights' in the room had been turned off. I'd had absolutely nothing to do with the house lights but try telling that to the fool!
I'd had just about enough of him and he said something derogatory about my equipment, to which I replied, "well, had I known I'd have been in the company of David Bailey I might have made more of an effort... oh, sorry, what was I thinking, David Bailey YOU AIN'T!"
He backed off after that.
2) During my second Christmas of DJing, I did some gigs for a real cowboy outfit. One of their clients was a Holiday Inn Express hotel, which had one of the pokiest restaurants imaginable and used it as their function room for office parties. The one gig I did at the hotel was supposed to be an 80s-themed party, which was absolutely fine for me.
I played non-stop 80s as background music and then for the first hour when the party started. Initially the 80s music hit the right note but the punters got bored. They were a nice bunch though, didn't complain at all but gave me a list of classic party tracks to play, none of which were released in the 80s.
What do you do? My response is to play what your punters want. I did just that and had a lot of happy people dancing to your usual party tracks including Dancing Queen, Let's Twist Again and The Macarena.
A member of barstaff for the hotel came up to me and told (yes, told) me 'stick to the theme' and walked off.
I ignored her. A different member of staff came up after 5 minutes and said, "look, you've been told it's an 80s theme, so why are you doing your own thing?" I explained I wasn't, all of the tracks I'd been playing had been requested. I even showed the guy the scraps of paper that the punters had handed me.
He said, "ignore them!" I got into an exchange along the lines of 'you're working for a hotel and you're telling me to ignore the customers... how does that make sense?'
Fortunately one of their customers came up to request something and the guy working for the hotel intervened, "only 80s music!" I said, "but that's not what they want." The customer looked like she was about to lose it, so I suggested she complain to a manager. She did, and I saw this bloke in a blazer, tie and shirt walking over with the customer towards the obnoxious staffmember. The manager looked annoyed. End result was I played what I was asked to play by the paying customers. I was glared at by the staffmember for most of the evening.
The hotel, or somebody from it, complained to the cowboy agency who I worked for. The owner didn't know what he was doing but tried to tell me I'd acted improperly and had 'spoiled the night.' It just didn't tally. I'd not received a single complaint from the people attending the party, in fact people had thanked me for playing their requests and I'd had people up dancing in a very poky restaurant for most of the evening. I'd done my job.
