Things that seem to be used less and less
- clothing irons
- wallets
- postcards
- handkerchiefs (I am not sure where you would even buy one)
- huge department stores
- multiplex movie theatres
- fancy dinner services and tea sets (my mother and grandmother adored theirs!)
- wallets
- regular milk (at some places in Stockholm you can only choose between oat milk and lactose-free milk)
- landlines
- business suits, particularly for women
- high heels during the day
- handwritten letters and invitations
- Physical Christmas cards
- keys
- cash
- postage stamps
- banks
- automatic teller machines
- post offices
- address books
and I don’t think there are such things as public phones anymore.
