What’s up with the harley davidson, jack daniels and western inspired interior of all barbershops?

I've been to a barber that served beer on tap and was a bar at night!

You sure you didn’t enter the wrong door and happened to walk in on a meeting? Buuut yeah, I guess the biker/viking/hooligan/americanfootball powpowpow is a thing, although I’ve seen a fair part of barbershops that doesn’t look like you describe. Maybe they are easier to spot? Just add some hops and you’ll have a local brewery too :)))

London

mine has giant plants, brutalist aesthetics and black and white decor 🤷‍♂️ would recommend when you’re in /london

They fit the western depiction of what “manly” should look like.

i shave my own head at home because i hate barbershops
