3,405. Transporting Produce
Hilchos Maaser 4:10
If there are two courtyards, one inside the other, either of them will obligate produce in tithes. If a potter's booths lead from one to the next, the inner booth will obligate produce in tithes, but the outer booth won’t. A shop will obligate produce in tithes just like a house.
Hilchos Maaser 4:11
If someone brings his produce from one place to another, the produce is not obligated in tithes even if he brings it into houses and courtyards on the way. Therefore, he may snack from the produce until he reaches his destination. This also applies to his return trip (i.e., if he goes back instead of traveling on to his original destination).
