Much as they won't want to admit it, there's a difference - in aggregate - between truckers and individual drivers. It's not hard to see the difference at a truck stop. Not allowing truckers at a rest area is no different from a fancy restaurant with a dress code; that restaurant is supplied by truck as well, but the driver needs a shower and change before dining. It's a spurious, bad argument. Truckers can go to Buc'ees as long as they're not in trucker mode.
