At the café Alkhimiya (“Alchemy”) in Odesa, they brought us the business card of a similar café, Bufet, along with the bill.
Note that the cards weren’t lying on the table: they were brought specifically with the bill. That’s why I noticed and remembered.
At Le Mon, a fairly expensive café on Bunina Street, the bill came on a little plate like this:
(Image lost: the plate the bill came on, covered in ads.)
Ads for water filters and some sort of windows, I think. It looks disgusting.
Conclusion: you have to approach guerrilla marketing wisely.
Now who, tell me, who, leaving a café, will take along a flyer from a company that sells filters or installs windows of whatever high quality? A flyer and a booklet!
But the idea is a good one! At Alkhimiya they get it. I might drop into their Bufet some time :)
P.S. Almost forgot the funny part: I put my own business card on that little plate at Le Mon. In revenge.
