- You are not charming
- You are not interesting
- You are definitely not funny
- At all
- Your attempts to speak the Russian language are in no way cute
- Or endearing
- Your desire to exchange money for goods and services does not in any way mean that you deserve respect
- Or politeness
- Or really anyone's attention
- At all
- You should be grateful to be tolerated.
- You know, in the way that people tolerate haemorrhoids
- Or genital lice
- At least until they can get hold of a decent ointment
You may not notice how much your self-esteem is buoyed by the dozens of tiny interactions you have each day, with shop assistants, baristas, waiters, receptionists (etc.) - the smiles (however forced), the polite inquiries about your needs (however insincere), the general sense that your custom, and indeed your wellbeing, might matter to somebody, somewhere...
... until you have it taken away from you, all at once. I'd hate to over-do it - it's not that you never get polite, good-natured service in a Russian service situation.
It's just... nearly like that.
