Yes, this is correct, as customers go to these sites, depending on time availability. In my country it is usually difficult to get an available space on weekends, but during the week, although it is always fluid, it is easier.There are some days when the salon gets more customers than other days so the salon owner manages prfits and losses because every thing is balanced in a week. If a salon gets a few customers on some days, it actually get more than required customers on some other days so this is how things are balanced.
