How many people were served coffee in the restaurant? ** The number of customers who were served coffee in the restaurant is 3/5*25 = <<3/5*25=15>>15
How many people did not buy coffee in the restaurant? ** If the total number of customers who came to the restaurant was 25, then 25-15 = <<25-15=10>>10 customers did not buy coffee
