I have stopped taking anything if I am going on holiday abroad as you can get everything you need in the supermarkets these days and I am trying to keep my packing down.
If I am going self catering in the UK I take quite a bit of stuff like TBags, coffee, cereals, salad cream etc as it saves spending time food shopping as I work everyday in my guest house my holiday time is very precious.
We are very generous in our guest house as the trays in our bedrooms have lots on them, coffee, decaff coffee, green tea, earl grey, red bush, PG tea, various fruit, camomile and mint teas, hot chocolate, biscuits. Plus if you run out we have a dish in the hall full of sachets that the guests can help themselves to.
