Seriously, there's some hogwash in the comments on here about these two, in my humble opinion!
So Alicja isn't keen on using toilets on public transport? Well many people feel the same way, including myself. I'm not someone who can go hours and hours without visiting the bathroom, but the thought of train and plane lavatories fills me with dread, given the condition of them at times. And because I don't want to use those bathrooms if I can avoid doing so, I don't drink a lot of liquid prior to boarding such modes of transport.
I have never seen anything to lead me to think Alicja has an eating disorder! What I have seen is that both Steve and Alicja appreciate and enjoy very 'average' food from cafes and take-aways etc - the sort of thing that is not beyond the budget of very average people, like me. I realise they could possibly opt for healthier choices - and sometimes I shudder at what Steve's eating, and wonder if Alicja worries about his health - but then I say to myself that he's very active, and enjoys his grub, and she doesn't nag him, and they seem like a very happy couple right now and I appreciate their efforts to show what's out there, in the realm of budget travel, accommodation and dining options.
