Actors are also sometimes taken on a course to show them how to get the best effects with the smallest amount of make-up. Or at least some companies do this.
And with the question about actors touching you. We will not know this until a sign goes up on the outside saying that they will, or a speech from a worker of Thorpe. If they do not warn you that theya re gonig to touch you, it's illegal and will not be open for a long time. But Thorpe being Thorpe (by this I mean a major business) they will give warnings of it.
