In a particular village, only two barbershops exist.
The first shop has a handsome barber with a neat haircut who is handsomely dressed in clean clothes and is extremely humble with his body language. The place is clean and looks hygienic.
In the second shop, you can find a barber with shabby clothing. His hairs are weirdly cut and his clothes still have the stains from last night's dinner. The place is not clean as well and reeks a bit.
You visit the village for the first time and decide to get your haircut. Which barbershop will you like to go for that and why?
