You might be surprised how profitable gelat shops can be, even when used minimally. The gelat shop I added to Era has generated 563550 gelats as of right now, which is roughly $5,600 USD ($48 for 4400 gelats = about $0.01 per gelat). $5,600 isn't a ton of money, but I'd bet it pays the bandwidth bill. As long as gelat shops are done right (as opposed to how it was done on Zone), they work.
I'm using information from Era staff so I don't know if it's entirely accurate, but from the trend I saw before I was fired, it looks like it probably is.
