In order to be paid for flying, you must have a minimum of a commercial rating in the category and class of aircraft being flown. Sounds like you got to ride up front while at work and someone let you wiggle the sticks a bit, which is a lot different than having been formally trained. Ever performed a full-down auto?

Just diggin' yourself a hole now, you might want to quit while ahead. There are lots of Robinsons flown successfully every day, they have a fine reputation. 

You do qualify for a stay at a Holiday Inn Express, tho.
