When I was in grad school, I would sometimes do my studying at a coffee shop. It made a chance of pace from my grungy student apartment and it was an easy way to meet up with friends for informal study groups. On the whole, I am certain the cafe made a net profit off of being my cohort’s favorite off-campus study spot. But I am certain some individuals were more profitable than others. On a weekend you might have four of us ordering full meals, four ordering drinks, and two hanging out.
For me, I had no problem paying, but sometimes I would try to stretch it out. Why? In all honesty, there is only so much coffee and pastries I can handle in a day. I didn’t want to pay three bucks for a scone that would just be calories I didn’t need. I would have loved a way to purchase legit seat space without having to buy things I honestly didn’t want or going through the whole charade of pretending to nurse a cappuccino for an hour.
I could see some kind of good karma donation where five bucks would get me drip coffee and free wifi, and maybe 10% of the total profits from that being donated to a local access or education organization, or maybe being put towards free events put on by the cafe. Make it seem like a fun, positive, communal thing rather than a punishment or a donation straight to the owner’s bank accounts.
I was also very aware of the space I was taking up, and I really appreciated having access to low-profile bar spaces where I could set my laptop and not feel like I was taking up a valuable table. You can cram a lot of people onto a small window bar, and I liked that I could sit there and get my work done without feeling like other customers or staff were giving me dirty looks. I was also a fan of large communal tables where you could take just one seat rather than claiming the whole thing. If you don’t have these kinds of low-profile workspaces, I’d strongly consider creating one.
Anyway, it’s a a balance. If, in trying to manage a few people, you alienate an entire group, it could be disastrous. My undergrad had a cafe with this problem, and they implemented a “no study during rush hours” policy. The student population saw this as a student vs. townie thing, it blew up in the student papers, and there was an immediate student boycott. The cafe never recovered their popularity. Likewise, it’s better for the cafe to be busy than empty, but you obviously want space for customers to sit. Whatever policy you have needs to keep this balance, even if it’s not the “fairest” policy.
The issue is that cafes really don’t have many ways to distinguish themselves. Coffee is coffee, and the food is rarely special enough to make the cafe a destination on it’s own right. Cafes are selling their unique atmosphere and community, and you don’t want to disrupt the illusion. Instead, you have to make it like Disneyland, and make the purchases seem like they are part of the atmosphere and community, not something that takes you out of it. Whatever you do, keep it cheerful, and don’t make explicit references to revenues and profits. Make it an opportunity for people to feel a part of the cool vibe of the cafe, rather than a way to snap people out of it.
