We sell coffee, decaf, herbal and other flavored teas, hot cider, irish creme cappuccino, french vanilla capuccino, and hot chocolate. The 3 head cappucino machine is a recent and expensive acquisition - but I am now totally hooked on irish creme. I am still working on building up a substantial clientele that is hooked also.
After all the research that we did to find a machine that fit our narrow counter, we still ended up with one that didn't fit after all. It is now located between the boxoffice and the popcorn machine rather than in an obvious place. I ended up making signs on the computer advertising its existence and people are gradually figuring it out. We charge $1.25 and $2.00 and will have to sell a lot to ever cover the machine cost, but we had been serving cappuccino from individual packets from Sams Club which we mixed in a mixmaster. The problem was that Sams quit carrying them.
We serve all of this stuff as a matter of philosophy. We try to have whatever our customers want that we can find a way to make reasonably fast and efficiently. We would much rather serve it than have them bring it in. We also do it as a way of differentiating our theater from the competition.
Now that I have the cappuccino machine I would rather not make coffee but still get fair number of requests for it. We purchased a two warmer Bunn coffee maker. We always have a pot of hot water on and the coffee is made on request. We just keep a pitcher of water on hand to pour in and get a filter pack of the desired coffee from the under the counter. Takes 30 seconds. Customer gets to do cream, sugar or whatever themselves. Avalon is right that tea is probably quickest and easiest for the theater and buys you a lot of goodwill for very little trouble. We have worked out ways to do all this even when we are busy. Tea & hot cider are $1.00. Coffe is $.75 and $1.25.
No - we don't make big profits from the whole kit and kaboodle, but we DO make happy customers. Ours is a competitive market and we use our concession stand as one of the reasons to choose our theater whenever possible.
