you want to try working in a post office, especially at car tax time, I've lost count of the amount of abuse I have to take, just because someone can't read the words CERTIFICATE OR COVER NOTE of insurance and bring the bloody schedule, and then swear at me when I say I can't do it for them!
Either that, or I get abuse when they try and cash their giro's early!
I have worked in a shoe dept too, and know what it's like to serve someone who think you are their personal slave for the day, and don't even know how to say please and thankyou!
