Buying food for me at the local grocery stores is a damn routine now. I have them mapped out in my head as far the ones here. I used to work at a Publix anyways when I was 16 to when I left for UCF at 18, very used to those stores and they are a big chain here. That is where I met my first girlfriend, she was a cashier.
Glasses I just walk in there, do the exam and pick out some frames and buy the shit and leave. I don't do it as regularly as I should maybe. I am only 28 but I have lost and broken glasses several times anyways. Had to get new ones, either that or go in to get my frames fixed which has happened a few times as well.
