Programming Language is Python

Pearl's Pancake Pad is a growing restaurant business, and they'd like to upgrade their existing pen-and-paper system for tracking tickets to a digital point of sale system. They are asking you to design and build that point of sale program for them.

The point of sale program must:

• Allow the waitstaff to input the table number, and the number of diners at this table. Each table can seat up to 4 diners.
• For each diner,
  • Display a menu of at least 7 common breakfast items, including types of drinks and entrees, with prices displayed. The menu is small, but the quality is high!
  • Allow the waitstaff to enter the items the diner has ordered. Each diner may order as many items as they want.

• After all diners at this table have ordered, display the before tax total and total with tax for each individual diner (sales tax is 8%). Also, display the total with tax for the whole table, and suggested tip amounts for 10%, 15%, 20% and 25% service qualities.
• After a table is complete, the program should restart at the beginning, and continue until the manager selects quit. Before the program exits, it should report the total amount of money that should be in the register (ticket totals + tax for the entire day).
