When I worked for a call centre, and I got a particularly bad customer, I used to doodle on my whiteboard of what I think they would look like as dogs.
So if you've ever had the opportunity to speak to me at my old job and you've called 5 minutes before closing to tell me that you've not paid your phone bill and we're going to restrict your services because it's the 5th time this year, and then personally blame me for causing you stress when I've explained there's sweet FA I can do about it, the billing department is closed and we had been open ALL DAY to resolve this issue, I probably drew you as a dog. If you ever rang me to tell me your broadband is down and I tell you that it'll be 2 days before we can send an engineer to you, and you tell me that's not acceptable because now you've got to entertain your own kids, I drew you as a dog. If you ever rang me to tell me that your internet speed is 2Mbps but that's because you decided to buy your own land at the arse end of nowhere and build your multi-million pound modern mansion there where there's no street registered, and all you can get is copper, but somehow that's OUR FAULT, dog. If you ever rang me to say you can get better prices on comparison websites, and want me to magic up a discount from my arse and complain incessantly when I can't instead of just using the comparison websites you've preached about, dog. If you ever rang to tell me that you've got a problem entirely within your own domain, but you expect me to send an engineer out for something out of their remit because you're technologically illiterate and then start screaming down the phone at me when I say they can't help you connect your wireless printer to your PC because that's not our problem, toothless chihuahua. If you ever rang first thing on a morning and expected me to be peppy at 8am, when I finished my 10pm end an hour late because the last person I talked to wanted to ask "one last question before you go", dog. If you ever started a sentence with the statement "I've looked on your website, but I can't see..." and then suddenly expect me to see what you can't see, dog.
Bet my colleagues just really thought I liked dogs with how much I was doodling them.
