Perhaps not overt, but a close friend ordered a $4000 shearling jacket from RL and sure enough the RL was on the buttons. He sent it back. I ordered an even nicer one, hand finished, from Orvis, for $500 less and it had superb horn buttons.
This has only happened to me once with a provider. We established a nice rapport via SMS. Then, as the day approached, he said that he was worth more than he quoted. I told him that I wasn’t comfortable with the new rates and he proceeded to lose it, accusing me of being cheap and telling me that he would blacklist me in his town. I simply cut him off after he tried to call me twice. Silly drama.
