Mexico corrupt?

I've been visiting Cancun every summer for 3 yrs. However, this yr I had quite the experience. I was offered illegal substances by one of the thrift shoppers. Fast-forwad 2 nights later -- my friend and I were able to snatch a cab back to the hotel- the driver escorted me out of the cab and proceeded to insert his hands underneath my skirt into my privates.. at which point I shoved him away. I get it.I was drunk..and shoving him was physically difficult, .. but is this normal behavior ?
