My shop is right here behind my home, so someone is almost always here to answer the phone.
In theory, hours of operation are 10am until 5pm, Tuesday through Saturday. Or maybe until 6pm. If the weather is nice, maybe 7:00. If the weather is really nice, maybe 4:00. Additional hours are available by appointment, special request, via bribery or due to natural disasters. Payment is by cash or check, coffee gift cards or other delicious beverages, depending upon either the time of day or direness of problem.
Heck, I live here. If you have a question, just give me a call and we can work something out. I usually answer emails within a few hours.
