NO ENVELOPES!!!

After waiting in a queue for a while at the Post Office as there were only two people on service, I was told that they are OUT OF ENVELOPES! I mean...aren't they suppose to be the home of envelopes? I had to rush to the nearest supermarket to buy one, but I was told that they are sold in packs! I had no choice but to buy a pack and quickly rush back to the Post Office, only to be told to wait in a queue again...! Talk about non delivered promise of service that will waste your time and money - REALLY DISAPPOINTED!!!
