Erm, well the phone number (03-321 56 40) googles to some dodgy online s3x drug chemists in Belgium etc areas.
The text seems to be a mix of French and Greek and the number if you drop the leading zero seems to missing a folloing zero, which would then give you a Greek international dialing code for Greece (+30nnnnnnnnn)...
The french is about travel sickness.
So putting my detective hat on with all that, I googled (lord knows why!) "greek travel sickness" and then a few variations quickly found.... hey presto....
Nice, I'm sure they make the bum(pun)py bus rides more fun.... Yes, DIY rectal travel sickness (I refuse to google how they work!) suppositories.....
