Has a teller at your bank asked why you are withdrawing a significant amount of cash?

I am having some work done on my property: excavating and concrete pouring. It is a relatively big job – about 20–25 yards of concrete – and involves an excavation crew and concrete forming and pouring.
Contractors love cash and are more than willing to reduce the price if paid in cash. I went to the bank today to withdraw $8k.

I ca:rried my own personal check and asked to cash it. Before the teller gave me the money she asked: “Are you doing anything fun with it?” I said :“Yes!” “What are you doing with it?” “I’m getting a car.” “Why does your check say “Barn” on it?” At this point I came clean and told her it was for a concrete job for my barn. I asked: “Why are you asking me this? The money is there.”
She said “We are asking all of our elderly customers to make sure they are not being scammed. We have had so many attempted scams recently that we are making it a policy to ask the customers.”
She gave me the cash and I thanked her for protecting us.

I found the whole transaction shocking: She thought I was elderly!

Have you made a withdrawal of greater than $5000 cash recently? Did the teller ask you for info?
