A very popular ice-cream shop recently raised the price of an ice-cream soda by $0. 20, from $1. 80 to $2. 00. Within a week of the price increase, all of the waiters-and waitresses had quit.
The statement 'Regular customers continued to frequent the shop, despite the increase in the price of ice cream sodas' would most help to explain the resignations of the waiters and waitresses.
