when customer says 'This is bullshit'

I'm not sure has anyone get a customer that says 'Look, this is bullshit' before???? I do and almost everyday..Some say worst than that..Honestly...It is sick and tired...To those customer out there, it's not my fault if what you see and what is available is not the same...We can't keep on offering the same...We are doing our job...And remember that you are not Bill Gate that has your own company..You're just an employee like me who rely on your company for your montly pay. You're nobody so its better for you customers to watch what is coming out of your mouth...Don't be a rude asshole..Think twice before you want to say anything....
