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 'The waiters and waitresses received fewer tips than before because the increased price deprived customers of change that many had left as tips' would most help to explain the resignations of the waiters and waitresses.
