As long as there are plenty of ppl whether in ClubSNAP (most of the time) or else where (even some pro) offer "unlimited" instant print on the cheap using selphy printer. There will be ppl including established companies and Stat board, govt agency taking their services. Events companies also are partly responsible for this low rates offering "unlimited" prints.
It is mostly a hit and run job, cos many such events like D&D and Party type, happen in the company once a year and hence even the clients in the end are not able to get the prints it is already over.
As pro, there is no point wasting time on such issues. I don't even bother to reply to any services wanted in CS cos the market segment here is different. (BTW In case anyone think I am contradicting myself, I got complimentary free advertising from the admin as such you can see my advert in CS - that's all)
I find it is difficult to make Instant print as your bread and butter, unless you are niched in certain market eg, "Livestudio" very established in the high end market. or do those graduation instant print type for Poly ITE etc. I do have a Noritsu Printer which was bought for a project (couple of years back) and already paid for itself in that project. As instant print is not my bread and butter, I aim for market that cannot afford mistake in getting the shot, in printing and very time sensitive eg, impt conferences, seminar (mostly govt) like ASEAN Health Minister Conf - group photo taking and instantly print in 6R and packaged - these events do not come often, but clients do not go for fly off the mill selphy printing type. Likewise I do not do weekend events, party type, even company D&D at year end, cos there will be tons of holidays students offering cheap "professional" event photography - so why compete with them? unless you want to be in that market.
My point is focus your energy on the positive and look for a market segment where competition is different, then go into it. No point wasting time and energy ranting...... My 2 cents...
