I wandered in to purchase a mirror for my bike as I'm new to Pittsburgh biking and the lack of bike lanes and narrow streets means being able to see behind is really helpful. The owner was extremely helpful in suggesting mirror options, especially since I was thinking of getting a helmet/glasses mirror, which he recommended against. He offered to install, but I had walked over and also thought I could install no problem. I get back and my handlebars required cutting the rubber to install, which was more complicated than just popping off the end cap, so I hopped on my bike and rode over. I hadn't checked the hours (and also didn't know what time it was until I looked at my phone), so I was surprised when the door was locked. They close at 5 on Saturday and I got there at 5:07. Crap. I checked opening time for Sunday and was about to head off when the owner came around. He had left his phone inside and very graciously helped install the side mirror, which ended up requiring new grips because mine were solid in the core after he cut off the end. The owner was super friendly, and went out of his way by staying open to help me out with something that could have waited. I have been to bike shops in other cities and I have to say this owner was the nicest I have met- I highly recommend and will definitely be back!
