It would really annoy me also to have a tea bag in when drinking.
I do not understand why anyone would leave it in, and have never had a visitor who leaves it in and drinks, as it could also make a mess!
No, that would make the brew too strong and get in the way while drinking. I know someone who leaves the bag in and then reuses the bag and although the boiling water probably kills the germs the idea of drinking tea made with the bag that's been in a cup someone else was drinking out of grosses me out.
I have 'Tea Bag Tongs', & squeeze liquids remnants into my mug.
I've a pottery-crafted 'Tea Bag Holder', shaped a bit like a 'potato-sack', into which I fold paper 'serviettes' unused from Coffee Shops, when I've had a meal etc. this absorbs leftover tea bag liquid, & holds tongs.
I then cut-off tops of tea bags, where string & staple are, which goes in rubbish. Remainder of then tea bag is put into compost for my 'Crepe Myrtle'.
Lately, no. I've been turned off from tea bags as I now only drink tea leaves. I tried tea leaves over a year ago, and the man who served it to me said I'd never go back to teabags, I thought he was just trying to sell me some of the tea mixes, but he was right, I can't go back, so I'm afraid this is a no for me.
I like to remove the tea bag before I drink my cup of tea. I've never thought about it but if someone served me a cup of tea with the bag still in it....I'd probably walk to the rubbish bin and deposit said bag.....in....it.
Sometimes I enjoy making tea the old fashioned way - loose tea leaves, 1 for each person and 1 for the pot - with boiling water in my tea pot.
In addition to my reply to the previous comment, and something that would bug some people is something another person loves to do. People are fascinating and it's great to have this hub to share reactions, experiences and opinions.
