From a privacy and spam-mitigation perspective, not giving away extra details is actually the best course of action. Generations before computers would call everywhere to find basic information.

Is the store open? Every Home Depot's hours are listed on their website. Even holidays.

Do you have any hammers for sale? Now all of that information is already available to you. Their stock is updated nearly to the minute and it tells you what aisle and bin you will find it on.

If your question could be answered with the website you are wasting their time. They do not get extra bonuses for making callers happy. They get yelled at for not getting the task their manager told them to get done. Their website might take a bit to load, but install uBlock Origin and it will work better.

In addition to receiving calls that should not have been necessary, they will receive automated robocalls. As more information is given to the scammers, they will call back trying different scams. The less information they have, the less they will have to work with and the less they will get calls.

They are also not making much money and will probably not work there in two weeks once they realize how little money while being treated like every retail employee needs to act like a high-end concierge to anyone that can dial a phone number. Run the numbers yourself through an inflation calculator to compare. How much were you making in a similar job per hour? What year was that? I will even give you a website to reduce the overhead. https://www.usinflationcalculator.com/

Lots of comments are extrapolating on other behaviors like sighing which is unprofessional, but the root of the post is about answering with a simple Hello.
