Since Hugo’s is a couple of blocks from my house, I can let you know that it is a tiny two window classic hot dog / taco stand set up:
Very small: tiny with two small windows, one on the left to order, one on the right to pick up your order. You NEVER “WALK IN”....you walk up to the order window to order, then walk to the pick up window to pick up your completed order. Then you may lean on a ledge to eat , take it home or sit on a bus bench.
Having worked at Dodger Stadium in the summers selling hot dogs while I was growing up, I can safely say, people ordering thru the TINY window are close and one might be concerned at droplets aimed their way while ordering.
Why not wear your mask while face to face with another person who may have a higher level of concern? Then remove your mask to eat? it’s really easy.
I, personally have been going thru this thing with a low level of concern. yet I do nit go out as frequently. I have friends and aquaintances who have gotten this flu and know of a small number who have died.
As a result, I do wear my mask, do my errands and come home.
