Question 5. What are all the people doing out on the field at halftime?

It’s customary at polo matches to invite the public onto the field at halftime to tread in the divots kicked up by the horses.  The custom has a practical as well as a public-relations value: the field is repaired for the teams by the time they begin the second half of play.  It’s not clear who was the first enterprising club manager to realize he had an abundant and cheap grounds-keeping crew at his disposal, but old-timers will tell you the job used to be done by hired help.  In the 1920s, for example, laborers at the polo clubs tapped in the divots after every period with a tool resembling an oversized croquet mallet.  Between games, wives of the polo grooms, many of whom were immigrants, could be found on hands and knees cutting dandelions and other weeds from the field.
