greeting cards could be sold from coffee shops etc that still look like a greeting card but inside they have a voucher for a coffee/coffee with a friend/ meal etc . The receiver takes the card to the coffee shop uses the voucher and leaves the card there to be recycled.
Cafe's and restaurant’s should have a Pot of tea ready to serve. They could even have strong and weak. It would be more convenient for tea drinkers and handy for county foke like my self who prefer a cup of tea over coffee any day.
