Tickets for a boat trip to Alcatraz
A couple with three children waited in line at San Francisco's Pier 41 to purchase tickets for a boat trip to Alcatraz. Others watched with varying degrees of sympathy and irritation as the young children fidgeted, whined, and punched one another. The frazzled parents reprimanded them to no avail.
