Add a confirmation on X key (Spoiler Alert)

I upgraded Parlor to Funeral Parlor. The next day I got the X Spray for the first time as well. I went into the Funeral Parlor, before I got my 5 gems for free, I accidentally clicked on X, and it got removed for an entire week (it was Tuesday).

Removing an upgraded floorplan accidentally was really game breaking especially a strong upgraded one. I was really enjoying the game, but now I feel so defeated...
