The large station to which I commute has taken to making regular announcements, advising customers not to take big cases onto the "eskewlators".
I think you'll find that you meant escalators.
AIBU to be driven insane by this? The announcements at this station have also featured "sickth" (sixth) and "illuminous" (luminous).
AIBU to be driven insane with irritation? I suspect that I already know the answer...
