(Must be old, as there's no discernible Indian accent from TS...)
Customer: "I'm having a problem installing your software. I've got a fairly old computer, and when I type 'INSTALL', all it says is 'Bad command or File name'."
Tech Support: "Ok, check the directory of the A: drive. Go to A: \ and Type 'dir'."
Customer reads off a list of file names, including 'INSTALL.EXE'.
Tech Support: "All right, the correct file is there. Type 'INSTALL' again."
Customer: "Ok." (pause) "Still says 'Bad command or file name'."
Tech Support: "Hmmm. The file's there in the correct place-it can't help but do something. Are you sure you're typing I-N-S-T-A-L-L and hitting the Enter key?"
Customer: "Yes, let me try it again." (pause) "Nope, still 'Bad command or file name'."
Tech Support: (now really confused) "Are you sure you're typing I-N-S-T-A-L-L and hitting the key that says 'Enter'?"
Customer: "Well, yeah. Although my 'N' key is stuck, so I'm using the 'M' key... does that matter?"
