This sounds so familiar, did you hack my inbox?
I’ll rant along anyway, imagine pretty much the same conversation, only that once I even had that one hopeful client, who then proceeded to send me a screenshot of another seller’s quote, as if I’d said I don’t believe him and want to see proof or anything - no, I just had lost the will to live and wasn’t interested in working with him anymore already before that … (and he got insulting, too).
Not sure what the problem is either; if someone does the same work for less money, and even without any extra amount for not just 24-hour but even 12-hour delivery, dropping anything on their hands right now, well, go for it, and don’t waste our time by throwing a tantrum. I suppose the issue is that they may well suspect that it might not be “the same work”, after all …
