So many shops here are staffed by young people, who seem to be half deaf because they have their music playing so loudly on the speaker system that my wife won't stay in there, or sometime won't even GO in there.

When you stop at the lights, the lowered car next to you is often positively vibrating with base-and-drums. Deaf youngsters, again.

Or they will be. A audio survey was done in the main street of how loud people had their earphones set. The average was at a point well above where a business would have to supply its employees with earmuffs, and well into the risk-of-permanent-damage level.
So it is going to get worse with so many clothears about.
