Because they're open every other day of the week! Gotta give employees some time off.
Friday and Saturday are the busiest days and everyone deserves 2 days off
Same for barbershop and beauty Salons, Mondays are just not profitable, many dealers have tried it to only find out it is not worth the efforts. Belive them, they are there to sell bikes and if Mondays was worth the efforts, they would hire the staff to work on Mondays. Money talks.
You could hire more employees and open monday. But it is probably not profitable.
Races are on sunday and they need time to get back from them
Hire more people.
