Press “no tip” and sue them for hearing damage…

Seriously though, as a non American I only tip when the service or food was exceptionally good for the given establishment. People do however get paid a decent salary here, so tipping is optional.

Yes, and it’s mostly the wind noise, because on my electric motorcycle I need them more than on my large touring bike with superb wind protection.

In my experience, you situational awareness is better, because all sounds are turned down, you can still hear everything, it’s just not as loud. Most of these attenuate the frequencies where the wind noise is more than the rest, which also helps.

The main reason why I say your awareness is better though, is that you have less fatigue when you aren’t constantly exposed to loud noise while riding, again in my experience.

The helmet you have also makes a huge difference, just like the bike. On a naked bike you’ll have more wind noise, whereas on a touring bike with a large windscreen, it’s mainly engine noise.
