Not as serious as some of the other stuff I've seen on this subreddit, but I'd like to ask nevertheless. 

I'm a high school student. Recently, a coffee shop opened near my school, and I've taken to going there a lot (almost every day I'd say). It's really peaceful and atmospheric, and is a nice change of pace from school. i like studying there (and I get a lot more done there than at home), or just hanging out.

I'm thinking of going there later today to do my homework, but I don't want to buy anything. I've purchased something every other time I've gone there, but as a high school student (no job) this obviously isn't good for me money-wise.

I'd feel bad for not buying anything though, because they are a business in the end, but I don't want to spend money. 

WIBTA if I went there and didn't buy anything?
