I use my own coffee cup for take aways, regardless of the coffee shop I use.
Most chains have a Christmas reusable cup out now, but I don't need to buy a new one, the one I have is perfectly adequate.
I have an issue with coffee shops in Dubai regardless of the chain. Every time I request a coffee to drink in, they automatically reach for a disposable cup.
This was obviously drunk here by a previous customer.
I've learnt to place my order as follows (size) (type of drink) and automatically add 'in a ceramic mug and don't warm it'
In the UK I always get asked 'to drink in or take away' but Dubai doesn't work like that. I think it saves on the staff having to wash up as it's easier to scoop disposable cups up and put them in the bin.
I stop regularly at the local petrol station for a latte, using my own cup. I often pick up a banana at the same time.
Whilst I ordered my coffee, asked for a banana, went to the counter and paid, then back to collect my coffee, this had happened.
Not only was my banana in a plastic bag, it was then placed in a plastic bag.
Sometimes I just give up.........
