I used to work at a semi fast food place when I was a teenager. We had a man that would come in 2x a week and order a Mr. Fabulous burger and want triple veggies (which I think is yum)
~ and then wanted his double beef patties on the grill for
NO LONGER than 10 seconds per side. The only reason he was agreeable to the 10 seconds was to melt the cheese
( I love steak tartar....but handling and freshness is paramount. Somehow I don't think the teens behind the counter at Mr. Fables were well equipped
)
