My time is worth more than $1.40

The local grocery has a deal going with the gas station: if you spend $100 a month there, the gas station will give you 10¢ off per gallon.

So I went to that station, not my usual, in the hopes of using this largesse. Now, the normal process for doing this is to park, wave your card in front of the pump, then pick up a nozzle and fill your tank, take your receipt (still on paper, sigh... couldn't they just email it to me since the pump knows who I am?) and drive off. Total time: about four minutes.

Here, it was: park. Go into the station and show the loyalty card to the cashier. Authorize a cash withdrawl in excess of my expected tank capacity cost. Go out and wait. Wait some more. Wait even more. Finally, the pump cycles and I fill the tank. Go back inside to get a second receipt, and sign to acknowledge that I've been reimbursed the overage.

Total time and accompanying aggravation: fifteen minutes. Total savings: $1.40. And that's not counting the extra time it'll take to balance my checkbook, because reimbursements are an out-of-flow accounting phase with Quicken. And it can't be worth their time, either, to go through this double-bookkeeping issue time and again.
