Is it bad that everytime a customer approaches me with a question I always assume something is wrong?

A lady approached not long after I made her drink and asked me what song was playing. It was some taylor swift song and I don't really know her music well as she's someone I don't go out of my way to listen to. Anyways before she even asked her question I blurted out flatly is there something wrong with the drink? Normally I only get approached to be asked for things or if something is wrong so this was a new one. Luckily a coworker is a swiftie and was able to identify the song playing because I genuinely had no idea.
