Yeah, Starbucks will do the iced americanos. The shop that used to be our regular place would ice any coffee drink for me as long as certain people were working. I've never been a big iced tea drinker, but when it's hot, I always crave an unsweetened iced tea like my grandmother used to make. It's good to know McDonalds do it. It's unsweetened like they do it in the States? I really can't stomach sweet tea. Blech.
Funny thing on the original topic. I always offer tea or coffee to workers, and I always did in the States if it was early in the day. Even in the summer I would offer hot drinks along with cold. Not sure why it feels normal to me. Maybe it's the upbringing thing.
The other day something reminded me of this topic though. We had a gas/boiler inspection, and it was a team of two guys from down near Brighton. We were the first stop on their day in London where they do as many clients here as possible. Our street is horrible for parking, so the one bloke had to sit out in the van. He used the loo (which is something that happens about every other time we have workers in) and muttered about not being able to get a cup of tea "around here" and I felt guilty. But it turns out he was just moany (old guy) and was just complaining about being outside. I didn't offer the other man a drink because it wouldn't be fair, but for a split second I thought "well, maybe I am meant to offer it the second they darken the door".
