LOL. Had it been a Japanese burger place... Rotsa Ruck. Makes me Raff. Outside of the Japanese culture and language the R’s are distinct. Inside they just don’t get L and R.
I laugh every time I go to an authentic sushi place and order a omakase chilashi. Not a bat of the eye or a smile. They don’t hear it.
I thought about it....
Reminds me of the WWII challenge passwords used by the Marines in the South Pacific. Words were heavy with “L’s”
