The ancient sinks.

Very different from the old days. The faucets were changed, for starters. The old faucets were tall, goose-neck type, that were so old they barely turned. The knobs were on the side and creaked loudly as they were turned. Another change is the noticeable absence of the ancient bars of soap! Those once-white bars were streaked with black grime, probably used twice in their "life", were practically glued to the soap holders.
Not much more can be said of these sinks other than the twice daily paper-towel-induced clogging of the drain and the method of students approach to wash in these sinks. The method I refer to is the way we would come down the stairs and then weave in and out of the rows of tables to get to the sink.
