We've all known that Mrs Doyle's obsession with the offering of tea in Father Ted is firmly based in the reality of a certain Irish social experience.
Witnessed this on a train coming back up from the country the other day; two ladies, one more elderly than the other by about 20 years. The younger asked her if she wanted a cup of tea from the buffet car. The older lady asks "are you getting one for yourself?" to which the younger says she isn't, thanks.
She asked again in the "are ya sure?" way. Again a very polite but firm thanks but no thanks. This goes on for 5 minutes until the younger of the women says "sure I'll just go up and get you one anyway. And does. And the elderly lady drinks it.
I witnessed the "glass of wine/guy and a girl" version of this in the pub the other night but that's a whole other story.
