I dropped a few items of food when buying groceries, and did not pick it up
Did you tell the grocery staff?
No, I didn't dare to admit it
It's ok if you dropped things by mistake but you should pick them up. It is rude and you could get kicked out of the grocery store.
I don't care if they kick me out. Food is cheap.
It doesn't need much efforts to pick the food up if you dropped it. It's not about if the food is cheap or not, it's about correcting your own mistake. You need to change your attitude.
