Hey Myusername...
I am sorry you feel disappointed, but I am so glad that you enjoyed a great Motorhead gig.

It does sound like a rip-off.
I am old enough to remember when in the late 70's, early 1980's, if you hung around early enough, you would get pulled into the soundcheck for free and have a drink with the band.
It happened to me at The Heavy Metal Barn Dance July 1980... I will never forget that... and a few other lesser occasions.
