Sometimes I will steal utensils from my work.
Why do you want to steal utensils from work?
I wants to eat at my house after work without those damn plastic spoons.
It is understandable that you do not like eating with plastic spoons but you should not steal forks and spoons from work to use at home. You should not steal things from work and should follow your company's rules and regulations.
In that case, I'm going to be very hostile to all customers.
Why would you take it out on the customers? Just don't steal, and follow your workplace rules-- unless you're okay with getting fired.
