Everybody at my local pizza hut walked out!

I placed an order like, two hours ago, couldn't get through to the store when I rang up, then eventually I got a call from presumably the store manager saying he had just arrived and was going to have to do everything by himself apologising. If it wasn't the manager then I feel so sorry for them and I think they should walk as well. If it was the manager then hopefully it'll be a lesson to treat staff better!
