I was at an Amtrak station this weekend. One of the pre-recorded announcements concerned carry-on baggage.
"All bags must be stowed in the overhead bins. Bags are not allowed on the floor or on the seats, especially in those areas designated for our handicapped passengers."
Wait, what?
Does that mean that they are less not allowed on the fllor or seats in other areas of the train? Perhaps only slightly not allowed in some areas and mostly not allowed in others?
It seems to me that once you tell people that something is "not allowed", that really ought to pretty much cover the topic. Leave it at that and move on.
