Arabic shop signs

After spending a couple of days in Jordan ( where most of the shop signs are in Arabic ), i came back to Lebanon and noticed that this is becoming less and less the case. Some shops have the English (or french) word along with the Arabic one, but in a lot of cases, the shop has an Arabic name, but it's written only in Latin letters ( like Tezkar, which means souvenirs in arabic).
Even more shocking is the second example, of the word mashrou7a (a specific way to make the traditional Lebanese mankoucheh sandwich), using the number "7" (mostly used in chatting online) to indicate this letter proper to the Arabic language !
