How valuable are you as a customer? [View all]

[jambo101]

I've been going to the local convenience store almost everyday for a couple of years buying morning coffee sometimes a muffin, quart of milk,loaf of bread, lottery tickets,gas for my 2 cars.
On Monday as i only needed a coffee i brought exact change along,unbeknownst to me the price of a coffee went up 10 cents over the weekend so when i got to the cash i was 10 cents short, i said to the clerk i'll bring an extra dime tomorrow,to my astonishment he said no can do need the exact price...Really? .
Obviously if my being a customer isnt worth 10 cents he wont care that i've taken my $100+ per week business across the street.
Kind of a shame these days 10 cents is worth more than a regular customer..
