How much money can one business get you to send to hostile nations?

Drove past Starbucks today, cars winding round the building in the heat.  A few months ago I wrote this:  Went to a business near by that sets next to Starbucks. I'm setting there and I see 6 cars in line at the drive-thru window. Not a very good consumer, only about 2 times a year do I go to Starbucks.  I walk in and plunk down $50 for a paper cup of coffee. I ask this kid about the cars. He says from 7am till 2pm there is always 1 at the window, usually the line is about 4. I don't have a stopwatch but I go outside and check my wristwatch, now there are 2, one leaves and immediately a new 2nd one arrives. This new 2nd car in line from roll up, order, to drive off takes about 5 minutes. Hmmmmmmm. 5 minutes at idle, hell that's zero MPG. New 4 cylinder cars burn 0.25 gal per hour at idle, larger 6 and 8 cylinder ones, older cars pickups and vans around 0.5 gal per hour. Since the cars in line are a mix, I say lets use 0.4 gph as average. Lets say there are always 2 cars there running for 5 minutes.
(Thanks to my math tutor Kevin from Notacynic, I made some changes, in blue.  Well the smart ass didn't find a math error, but a logic error, I had calculated 5 minutes per car with 2 in line, he pointed out the clock runs on only 2 in line regardless if they remain 5 minutes or longer, it's just two running constantly.  Still, the waste is significant, it's a lot of gas, a lot of pollution, a  lot of money.  Thanks Kevin, I'll buy you a beer, ha, I know you don't drink.  If someone else finds a mistake, keep it to yourself.)

 7 hours  07:00 - 14:00 
2 cars in line at all time
0.4 gph average idle burn rate
-------
5.6 gallons a day wasted at this one store up to 2pm
$21.50 at approx national average ($3.84 Reg)

364 number of work days store is open.
2,038 gallons a year are burned setting next to this building.
4,000 number of Starbucks with drive up window.
81,520 gallons needed if all stores with drive up have this volume.
$313,036.80 total cost
45% (of each $ at the pump that goes to foreign nations for crude oil)
-------
$140,866.56 amount of your wealth sent to foreign nations due to drive up window at just one coffee chain, for wildly overpriced coffee.
