Stop in for a cup of coffee

Glass came in for the Fargo yesterday. body shop buddy, says his cost $80 for the pair, plus tax. This pisses me off. I grab my phone, and use my calculator,add 30% and apply taxes. Drop $120 on counter and tell him dont argue. Sob always cutting me deals and he has people on payroll. I stood my ground this time. Btw,hes 6’3” and about 280.
