When you get a question from a customer support people, there is only one correct answer: "Let me check and I will get back to you".
Otherwise, you get into a position like me today.
I fix one program in a PowerShell script and the script fails on the next problem. Not my fault but I do not look professional here.
"Let me get back to you on this one" - and then you have time to test and verify,.
Answer right away and you will make another mistake.
