A Starbucks drive-thru episode

Someone please tell me why I act like this. Man, I did something soooooooooo STUPID this morning. I went through the Starbucks drive-thru, ordered my drink and then kept driving on through to get to that window where you pay and I BLEW RIGHT BY IT!!!!!!!!!!! I kept driving on to eventually get to the window and just couldn't find the darn thing. I was waiting for the light at the end of the tunnel and by golly, I was at the end of it all where you pass that signature Starbucks green drive-thru garbage can. Holy crap, so embarrassing. I wound up having to go inside and get my drank and the barista laughed at me!
