Easy Probability Question 1?

A contestant on a game show is given a choice of 3 boxes A, B and C. Two of the boxes are empty but one of them contains £1000.

The contestant chooses a box at random, but before she can open it the game show host stops her and says: "I will now remove one of the empty boxes from the two that you didn't choose and you may decide whether to swap your current choice for the remaining box."

What should the contestant do: Stick with her selection or swap it for the other box? Or doesn't it matter either way?
