Blister feet

My title at my job is a cashier, I usually expect to go in to my job, clock in and start checking. To my surprise last Satur day I clocked in to be told to go outside and push carts. I usually don't mind at all, sometimes I do...OKAY, I always mind going outside, getting sweaty, and and having to go back inside to greet my customers dripping in sweat, but this time was different. I went outside, in the middle of the day, in the pouring rain!! It was ridiculously horrible. To have to push carts in rain, while customers stood in my way while I tried to rack them up because they didn't wanna walk to their car in the rain. Why do people shop in the rain? Pouring!!! and they would not stop coming. I was out their for a good while and had 6 hours left in my shift, so yes I was wet, cold, moody and my feet were killing me from the blisters I received on my feet that day.
