that's standard operating procedure (cept the service dog part...doesn't apply to all)

i would make a loud enough indirect remark/joke if it bothered me along the lines of 'Got damn ...ya'll just gonna see Spot run all up in thru here huh'

but i'm rational...and would've seen it was a service dog and prolly ignored....

BUT if hipster ass Shaggy n Scooby came thru sittin at a table next to me and lettin the dog eat off their plate and out their mouth...i'd say somethin just like a chic would
