A friend was once horrified to hear me say 'na razie' to a colleague who outranked me so I stopped saying it to higher ups.
HAHAHA, hierarchy problems :D
Poles do have something with that, it's as if some people are higher ranked in society than others, and should be listened to, even though there is no particular reason for it. I often also get a "foreign pack" impression - I behave normally, put on a smiley face and generally speak in a very friendly way to everyone I meet, whilst the person I'm speaking to often looks bemused by my behaviour, and seems to ignore most of my gestures and comments, and sticks to the things that matter in the conversation in a very strict way. In England you don't get this, you can speak openly even to strangers if you're lucky, but in Poland you've got to stick to the pack, if you know what I mean, you can only speak like this to people you know.
