People in high rise buildings who stop a lift which is going up even though they want to go down. And vice versa. Why? People who continuously say "obviously" even when it isn't obvious. Telephone staff who repeatedly say "unfortunately" even when it is clear that they are not one bit bothered. Telephone staff who ask if there is "anything else they can help you with today?" in an attempt to infer that they have helped you with the particular issue you caontacted them about. Telephone staff. Announcements which apologise for any inconvenience which "may" have been caused, as if there might be a possibility that none has been caused.
