Do you work in, say, a bridal shop, and you need to make people feel confident? “You look fabulous in that!” “That is so you!”
That’s really about the only scenario I can think of-- a job that requires indiscriminate flattery, although technically, there’s always enough ways to honestly complement someone without being insincere.
I once bought a car from a certain dealership. The salesman had promised me a free loaner car if my car is in their shop for more than 2 hours. I still remember the first time I went there, with a toddler and an infant in tow, depending on that loaner car to get us to the library so we could spend our four-hour wait time in more comfortable surroundings. They refused to honor it, and I got to sit in their waiting room with an infant and toddler for half a day.
That day was the last day their shop touched my car. I will never buy a car from them in the future. And they don’t get good recommendations from me whenever the subject of car-buying comes up.
I don’t do business with liars.
