I think it says a great deal, much of which has been pointed out.

I suspect many of our current mechanic friends here have never seen such treatment on a bike presented for service. Certainly, I never saw anything like it in 10 years of wrenching. The responses you're getting are based on the seemingly irrational fear of damage that you seem to have, and the (to me) inane solution you've come up with.

If you feel strongly about it, why not remove the tape, bring the bike into the shop "naked," discuss the issue with your mechanic and ask if you could tape it up in front of them?
