A baker. In the back what I think is the phrase BISMELLEH AL RAHMEN AL RAHIM, used to pray that an enterprise is fruitful. You can see it on houses, but people may also use it when starting cars, opening the door of their shop in the morning, or firing up an oven. Here it is done in ordinary lettering rather than Arabic.

The WIkipedia has on this subject: "It is sometimes translated as "In the name of God, Most Gracious, Most Merciful". This phrase is recited before each sura, except for the ninth; according to others it constitutes the first verse of 113 suras/chapters of the Qur'an, and is used in a number of contexts by Muslims. It is recited several times as part of daily prayers, and is usually the first phrase in the preamble of the constitutions of Islamic countries. It also forms the start of many dedication inscriptions on gravestones, buildings, and works of art, which go on to name the deceased or the donor."
