I just spent an hour on the phone with an elderly customer who was having trouble finding ebooks for her Kindle. She was looking for romance novels, but she couldn't figure out why it was only showing the extra steamy ones. Turned out she'd set her reading level to "mature adult"! 'Because that's what I am,' she said...
One of our regulars complained to the tech desk about all the cell phone use in the liberry. Then she came down to the ref desk and tried to make the same complaint. Instead of saying there is no end to the cell phone use, she said there is no end to my complaining!
An old lady asked me if there was a tech person on staff who could help her with her computer. I told her that we don't have a technician at the branch, but I could help. She said, are you sure? Usually there is someone quirky who can help me with my computer questions.
A woman about 60 asked me about the concert scheduled to occur next week. I showed her the description on the calendar and said, "this month the concert will be jazz music." She said (loud enough for others to hear), "oh €%#~, I hate jazz!"
