Are you allowed to buy cut up fruit from a grocery store? 🍉 🥭

I went into a store and I see they sell over there  some cut up fruit. Can I buy it? It depends what   type of store it is. If it's like a supermarket,  then we assume they have dedicated knives. They   have a separate fruit section where they cut  up the fruit. They have cut up watermelons,   let's say cut into quarters or other types  of fruits like that. So, those are perfectly   fine to buy. And aside from the fact that  they have dedicated knives, of course,   they cut so many fruit at a time. They cut up  hundreds of watermelons to put out. There's really   no question. If you go into a little store, just  a corner type of store, and they have over there,   you know, maybe one watermelon that they have cut  up into four pieces, then one should not buy it,   it's unclear what type of knife they have.  It could be use the same knife from the deli   counter to cut the watermelons. If the store is  selling things that need to be checked for bugs,   such as, let's say, strawberries and things  like that, we know it's very complicated to   properly wash them. One may not assume that  the supermarket or the store did any such   cleanings and therefore one should not buy  berries, or strawberries, things like that.
