Note that the folks at EWR finally have the system down now. I suspect CLE also are used to seeing Gate Passes. The TSA does not know it is a gate pass to go to the PC. There are other reasons for issuing a gate pass. They are used to seeing them and to a TSA person, a gate pass is the same as a ticket. They will just look at it, check your ID, initial it, and move you on the the scanner lines.
