If there’s one thing I was missing in the US, it was the efficiency of the Post Offices. Get a ticket, wait 5 – 10 min maximum during busy time and get your work done. The post office in Lausanne Gare CFF is spacious and has a philatelic shop. As many Post offices in Switzerland, this office has a pretty decent size Post Shop where you can buy electronics and office supplies. The hours are great as well. It usually open until 8pm during weekdays and 4pm on Saturdays. The cons are that they don’t accept any sort of debit or credit card Visa, Mastercard. They accept only cash or Postcards payment. You can nevertheless go down the escalator to the nearest ATM to withdraw some money.
