I'm sure all this smuggity-smug-smuggery reassures the OP, but the point I think he was grasping for - which some won't, we hope, ever need to consider, having breakfasted at dawn to allow time to pack their Pandora's Saddlebag for every eventuality - was "Aren't some bike shop owners dicks?" And I think the consensus among cyclists is (one at a time now, trollikins, don't all crowd round yapping), "Yes OP, that's like life isn't it! Some people are just dicks. And don't give you stuff when you need it. Sorry to hear about your plight. Had I been passing you could have had my rolled-up tenner I have stuffed up the crack of my arse For Emergencies (in a ziplok of course - wouldn't want faeces anywhere would we, ha!ha!?) so as to rescue you from your unfortunate embarrassment and see you on your way, all plumply retubed and inflated."
And breathe, everyone. And relax.
