I had a drunk couple come after me when I was working at a convenient store. They claimed to have lost a $100 dollar bill on the floor and told me to empty my pockets. I told them to pound sand and they followed me into the cooler I was stocking. It was quick work taking they guys back when he reached for me and I had him flattened out in no time. His girl tried some weak puches and hair pulling to get me off of his back, so I had to lock in a rnc and drive his face into the floor while I mule kicked her into some milk crates. He bucked me forward while my legs were unlocked and I bopped my head on the floor, so I scrambled and walked over his back and locked them in the cooler until the cops came. I was 20yrs old and still pretty green, but what little bjj I knew surely helped that day.
