I found the article to be ludicrous as it is so seriously short of tangible facts.
Without consistent reference points and direct A to A and B to B comparisons - not to mention a control group - it's a waste of ink, paper, pixels and reading time (all swipes at the authors of the study - not at Marshall for posting it.
It is not clear whether women were held up by male staff because the men viewed them with contempt or because the male staff members were flirting furiously. The "contempt" explanation seems more likely, as the extra time that women have to wait seems to increase when the coffee shop is busy. Who would take extra time out to flirt just when the lines are longer?
I can't speak for other shops but the folks I work for have four stores and about 15 front line employees - only three of whom are male. One of those men is me.
Based only on my own totally subjective experience I can state definitively that any customer who is in a hurry, has their money out and ready to go, states their order as they step up to the counter, and is not inclined to engage in any small talk - will have a shorter wait time than anyone else.
This assumes the elapsed time to be from the moment their "turn" comes to the moment they have change or a credit card receipt in hand and the next customer has engaged me.
Gender is really irrelevant.
