Post Office Credit card anyone?...

"Do you have a credit card Sir?" said the nice lady, rather awkwardly I sensed. "Yes I do and I'm very happy with it!" Came my reply. "Did you know that the Post Office offer a credit card with supadoopa interest rates and 0% balance transfers...." was her rather feeble repost, spoken very half-heartedly, as she probably sensed my cynicism. Inside you feel like saying, "for God's sake I just want to post some letters and parcels so just get off my back will you; if I want a credit card, I'll bleedin' ask at the bank or respond to a junk mail out leaflet, you people ar ethe last place I'd come to!" but you don't actually say it, even when they persist. Then there's some guy standing at the door as you walk out, you have to avoid his gaze otherwise he'll try to sell you another card, or Post Office Insurance or a mobile phone contract, maybe even Post Office double glazing! It's becoming like that scene on the great 1970s classic comedy film, Airplane, when the trouble shooter arrives at the airport and has to knee-drop and karate chop his way through a sea of charity collectors in the airport terminal before he can get to handle the crisis. Please Post Office just do what you do best, leave us alone and stop being greedy by selling us stuff we don't want....
