What advice would you give to a foreigner visiting Russia for the first time?

Based on the provided text, here's some advice for a foreigner visiting Russia:

• When Visiting Someone's Home:
  • Bring a gift (cake, chocolates, sweets, or flowers - an uneven number).
  • If there's a child, bring a small gift for them too.
  • Dress casually.
  • Remove your shoes and wear house slippers (tapki).
  • Compliment the host, but not too specifically (they might feel obligated to give it to you).
  • Avoid crossing your legs or putting your feet on furniture.
  • Never refuse offered food or drink.
  • Thank your host.
• When Travelling:
  • Offer your seat on public transport to those who need it more (e.g., mothers with children).
  • Keep your feet on the ground, not on the seats.
  • Don't eat on public transport.
  • Men should remove their gloves to shake hands.
  • If travelling with a woman, carry her bags and open doors for her.
