Staying at the FI Gurnee, IL.

Checked my bill and noticed a $1.50 charge for "Safe W/limited Warranty"
With all the strange taxes in IL, thought it might be that, but price was whole number.

Asked front desk and it was a charge in case I used the in-room safe?
Quickly revered the charge (with a code, so they must do it a lot.)

Got me thinking, what other strange "extra" charges have you seen hotels try to slip onto your bills.
