Client asks for STR Discounts we said no and now he is complaining about everything

[Shanel Dial]

We have someone staying in our STR this weekend. They asked for a discount before booking and we didn't give it them. Now that they there are there they have complained about bulbs being out and other small things and also say the internet doesn't work. We are not in town since it is a holiday weekend, however we did check the internet on Monday and it worked just fine. Wondering how you all would handle this as it felt from from the start he was trying to get a discount.
