They always tell you in business that you should never burn your bridges. This is actually very difficult, as you will sometimes come across such dreadful people that you will find it very hard to do anything but raise your longest finger in their directions.
However, what must the nice people at T-Mobile USA be feeling, now that news has emerged they will be acquired by AT&T?
You see, T-Mobile seems to have spent quite a bit of time and money telling us all that AT&T's service is, well, worse than a lobotomy in the open air, without anesthetic.
You must have seen the ads. They feature a nice lady in a dress (Presumably someone demanded a slightly younger Catherine Zeta-Jones) who ridicules the allegedly tortoise-like qualities of AT&T.
