What’s a reasonable price for a men’s haircut?

I’m a middle aged white guy with questionable fashion sense. I’ve been happily going to Rudy’s for almost 20 years. I have short hair and just get a basic cut “make me look decent”.

The last time I went I was charged $72, and still asked for a 20% tip. My first reaction was shock, but I’m genuinely wondering – what does a men’s haircut cost in Seattle?

Recommendations welcome.
