Is it ok to lie in a business context?

Pizza Hut: lying is good for business!

Consider Pizza Hut. When you asks how long it will take to prepare the pizza you ordered, the waitress will say "20 minutes." This is called the "standard waiting time." Staff are instructed by management to tell the customers that they will get their pizza in twenty minutes. The "standard waiting time" has nothing to do with how long it take to prepare the pizza, especially when the restaurant is crowded!

Why? Assume the waitress says 30 minutes. About 10% of the customers would leave and go the Mac Donald's or KFC. Assume the restaurant is crowded and the waitress says 45 minutes! About 30% of the customers would leave. And what if the restaurant is very crowded and the honest waitress says 60 minutes! The waitress would be fired because 50% of the customers would leave! Therefore, sometimes lying is good for business!
