Dh, my friend and I are going to a big sporting event in about 6 weeks time. We go every year, but because of work commitments (my friend is a Dr) we never know for certain that we are going until about this far out. As a result it's always a bit of a scramble to find B&B or hotel accommodation, but that can't be helped and we always get something sorted.
I emailed all the B&Bs on the event's own list over the weekend - as expected most are full and replied with standard emails saying so.
However, one of them (small hotel) wrote back saying "We're fully booked. TRY BOOKING EARLY NEXT TIME AND YOU MIGHT GET SOMETHING". 
I know it would be better to book early, but I can't and I don't believe I'm the only person who can't. Added to this, the event list has a facility for the accommodation providers to update when they are full, making for greater convenience all round, but NONE of the B&Bs had done that.
AIBU to think it's a bit rude to reply in shouty caps to a potential customer?
