McDonald's rampage at Disneyland

[snopes]

Comment: Is it true that McDonald's is banned from the Disneyland Hotel
forever? I have a co-worker who says she worked for McDonald's in the
early 80s and they booked the entire hotel for a weeklong session of
training seminars. On the final day, a Saturday, many of the employees
partook of the free booze that McDonald's had offered and rampaged through
the hotel, breaking things and throwing chairs into the pool from the
guest rooms high above. Supposedly to this day McDonald's is no longer
welcome on Disney property (except to sell French Fries) and McDonald's
withholds alcohol from all company functions.
