it really depends on the lab u are going to. hard to define 'ordinary shops'. most neighbourhood labs can process almost all kinds of films (35mm or 120) even when they dun have the equipment. they just send it out, which may take some time. But... there are some that Dun..
so best for you to ask the lab u're going to.
Some of the labs list can be found here.
