I own a car dealership, and my customers usually look at the odometers of used cars to determine their value, so I change the mileage on cars with a lot of miles to make them more appealing.
Do you feel guilty about lying to your customers?
No, I only take a few thousand miles off the high-mileage vehicles. It's no big deal.
You really should be honest with your customers. If they find out you are lying, they will tell other people and your business will suffer because people won't trust what you are selling.
I've been doing this for 20 years!
I'm guessing your business isn't as successful as it could be. It's immoral to not be honest with your customers when you take their money.
