Allright, I am leaving this thread after this reply to you. It's obvious that what I consider impolite/sarcastic is not what the rest of the world seems to think (excepted for my wife. I told her en passant of this and her reply was "classic. What do you expect from a public forum in Internet?") and I just don't want to waste further time repeating the same concepts over and over, it would be ridiculous.
This is what I think ISN'T a rude and sarcastic reply to me:
"If I was in your shoes, I'd try calling them by phone as in my personal experience, I had the best success with it"
This is what I am SURE it's a rude and sarcastic reply:
"Pick up the phone and call them, dummy"
This is what I am sure at 99.9999% that it's a rude and sarcastic reply that someone tried to slightly conceal:
"They answered my phone call on my first try"
Finally, if you don't have an answer to someone's question (for the love of God, I am not asking if they have phones and are they answering them, I am asking for AVAILABILITY and PRICE RANGE!), I believe you should not answer.
If you do have an answer to someone's question and you answer, it's a good deed you just did. Shared your knowledge, you know.
If you do or do not have an answer to someone's question and just tell them the obvious, in a sarcastic/rude way, you are being an <insert whatever
insult you might find appropriate here>.
Merry Xmas to all.
PS: thanks for trying to answer my #2 question!
