Your customer is your paycheck.
Don’t be fooled by the signature at the bottom of your payroll check — the guy who signed the check didn’t put the money there — your customers did. No customers, no money. You should change your customer greeting to “Hi, thanks for the food!” your business is worthless, and your wallet is empty without funds provided by customers.
