I've found a good and affordable barber in Reading that appears to be run by two Polish ladies. In the 4 visits I've had, I've not had one bad hair cut, which is more than I can say for some of the more expensive 'trendier' barbers. On each occasion they ask if I would like my side burns levelled (they tend to go a bit wonky from shaving), which is quite normal and expected, but they also ALWAYS ask if I'd my eyebrows trimmed.
This is the ONLY barber that has ever offered this, and they've offered it every time I've gone. I know I have slightly bushy eyebrows - note eyebrowS (I don't have a mono-brow) - but I don't think they need pruning just yet. Maybe one day when I'm an old man and can hardly see due to the large bushes above my eyes (like this), but not now.
I don't know about anyone else, but this offer always strikes me as a little odd. Maybe it's what they do in Poland.
