I went to a used bike shop to help a neighbor shop for a bike. It was definitately a lot grungier than the LBS's I usually go to, and with a different customer base.
This 50-60 year-old guy came in with a knobbie MTB wheel. He had old clothes and a face that looked like it's spent too much time exposed to the elements. He commutes roughly the same distance I do on my direct route (4-6 miles). Like me, his employer lets him take the bike inside. His method for dealing with the cold is to have a cup of coffee at a White Castle near the middle of his commute.
Some of his bearings were shot. They repaired the wheel for him. He showed a five and two ones and then asked how much extra he would owe them. The wrench took the five and said that was the price. I'm not sure exactly what my normal LBS's would have charge him for that, but my guess is $20 to $40.
