I would dodge it. also i do not think the tavern would appreciate it.. so he could cast the spell but it would do more harm than good when he sets the place ablaze. To make it worse, it is not hard for me to step convieneantly behind someone. :p the place is quiet crowded..
(Also with ALL seriousness, Sexual Harrassment is on a whole other level and the comparison is crude! I Hope none of us have ever been raped before but the trauma of such is far more awful than a stolen book of any kind! sorry but to me i view SEX CRIMES AS WORSE THAN MURDER. A form of torture born from depraved people stripping someone's right to consent and humiliating them! Lets not make said comparisons please. More attune to a stolen car would be fair.)
