Today I had to.
It was awful.
Walk on the left side of escalators.
Stand on the right.
Stop taking up so much space on sidewalks with your massive shopping bags.
You don't need to walk in the middle.
I'm not fat.
And neither are you.
Please don't rub against me on the train.
Not all's bad though.
Thanks for quickly telling me where to go in your store to find the specific product I was looking for.
I was done shopping in 5 minutes.
