True, but they are professionals, paid handsomely to represent us. The pitch is their place of work and all they are asked to do is turn up and work for 90 minutes without embarrassing us all. A bunch of ignorant louts made monkey noises. Everyone knew they would. They do it because they get a reaction. So what? Turn up, do your job, ignore them and make a formal complaint afterwards if you feel the need. Take all the fun out of it for them if there's no response.
