My left rear tire was low, so after meeting a friend for lunch (at Sakana, which gets my next review of "YUM!"), I went to the gas station to use their air. I've had bad luck with these things, so I was trepedatious. Aaaaaand, for good reason - it did let more air out of my tire. Luckily, there was a Greulich's Auto Repair next door, so I rolled over and asked if they could put air in my tires. They said, "Sure!" As the mechanic was filling my left rear tire, he found a nail. No wonder that tire was low! He repaired it on the spot and off I went.Very helpful, and nice! I live considerably north-er and would go back down to this Greulich's.
