I encountered a delta force ticket seller on the high street in Cardiff on Easter Monday. At least I assumed he was DF because the UKPBA 5* accredittedlogo was on the literature and as far as I'm aware only DF sites have that for some reason...
As is the case with any salesman he was a little flexible with the truth without actually lying. E.g. claiming that they had a limited number of these tickets when i could see a huge box to one side. Technically true because there wasn't an infinate amount in there. A little more misleading was the pricing structure. "The paintballs cost £10 per hundred, but you get them half price after your first hundred". (although I can't remember if he said that was if bought by the box.)
Now £5 is about market price for a hundred paintballs, so its not really half price after the first hundred, it's more like double for the first hundred. Or an extra £5 entry fee with the first hundred. But again, not really dishonest.
To be fair to him, he was reasonably well informed, sufficently so to answer any punter questions - i didn't ask anything overly technical as there is no need for him to know that. And he didn't conceal anything from me, mentioning the cost of extra paintballs (and thus the implication that additional purchase might be necessary). On the whole if all ticket sellers were like this chap I would have no real issue with them. So if Gups has any way of checking who was running the stall that day, get him a pat on the back.
