How To Sell Beer To Strangers On Street #streetlife day 1

First night of my homelessness, I attempted something I'm pretty proud about: selling beer to random strangers on street.
Where does the idea come from? Well, simple, beer in pubs is generally expensive, some even dare to sell at 6 or 7 Euro a bottle (660ml). I studied some brands of beer in supermarket, I can sell smaller bottle of beer (330ml) and also bigger ones (660ml). Smaller bottle costs 0.56-0.8 Euro per bottle, I would sell at 1.50 Euro. Bigger bottle usually costs 1.20 Euro, I'd sell at 2.5 Euro.
I bought 7 bottles of variety of beer and carried to one of the most popular hang-out place to sell. Only one sold, and it's sold to a friend at a discounted price.

Problems: 1.definitely huge trust issues, I wouldn't just buy beer from a stranger on street myself
2.The beer is not cold enough: having difficulties accessing fridge (since I'm currently in homeless situation), I bearly had them cooled for an hour and brought there, the only stranger who showed interested lost it after trying the temperature of the beer.
3.Selling skills. I was far from being a smooth talker when I was selling. I got nervous, my voice turned a little "Jesse Pinkman", sounds like I'm selling meth in Breaking Bag. Oh by the way it's way easier to get strangers to trust the weed you sell than the beer on street.

I invested 7.8 Euro, had only 2 Euro of income, 5.8 Euro loss (me and my friends consumed some of the unwanted inventory)... well, I may be back, brothers, I may just be the no.1 beer seller on street next time, what can I lose, I'm homeless, brother.
