Does it bother you when people crack their back?

I do this quite often and something happened yesterday that made me wonder if I was bugging other people around me. I was studying in Border’s and I was sitting in a chair between two strangers. I had been sitting for a while and felt like cracking my back.. so I did. The guy on my right just turned to me and said “Nice.” The woman on my left made a sound like she was disgusted. (Her noise actually made me giggle to myself a bit.) So does it bother you when people crack their back? Do you care?

(If it is annoying, then I’ll try to do it less often.)
