I gave our kid* a voucher for christmas as I tried three counters, to ask advice for what was 'in' for girls of her age, armed with phone with pics of her in daylight in several of her favourite outfits to get an idea of the colours she wears...
Blanked at each one, and yes, I rolled up with a fairly loud and clear 'excuse me, could you help me' each time, one looked at me in the mirror without even turning around, two of them claimed to be busy, one vanished, one just made herself busy with endless shite til I went away.
There was no confidence issue, there was no looking at the floor or meekly waiting and hoping, but yes I do look like a sack of shite on wheels and I am aware of that. I had also gone to spend IRO £100 ish. Their tough titties I guess.
It isn't the first time, I've experienced it at a variety of vendors of a variety of products - one day at a trade show FIVE stands totally ignored me, in one case reaching past me to speak to the person behind me in the queue of people being channelled through.
That was a great day, I went to number 6 clearly looking a bit frazzled by that point... they were fantastic, smaller company, nicer people, they're now personal friends and I direct everyone I talk to, who needs what they do (and that is several hundreds of people each year), to them.
Those of you who have never had an issue, you can pretend all you like it's because you're confident, out-spoken, go with an air of someone wanting to buy, whatever you like. People DO judge, people assume things based on appearance and some of those people are rude fuckers, we're not ALL imagining it!
