Tim Harford looks at evidence that men get served faster than women in coffee shops and wonders of female customers are being discriminated against. My guess would be that this is our old friend the double-standard, rather that specific discrimination on the part of baristas. Basically, men in coffee shops are more likely to act visibly impatient and demanding. And this, in part, is because aggression is generally seen as a good, socially-approved trait in a man and a bad, frowned-upon attribute in a woman.
