Kashrus questions:
1. What hashgachos can I eat? This question may have to be reasked since it always changes (at least in EY – although probably less so in the US). It also has to be reasked when you travel to another country, or possibly another location in the same country.
2. What hashgachos can I eat at other people’s houses? This also may need reasking since each situation is different, and friends/family/relatives may all entail a different psak (and as the hashgachos change, of course, it also needs reasking).
3. Checking for bugs. This also is constantly changing, as well as being different for different countries. You also need to ask what to do when you’re at other people’s houses. And of course, it has to be asked for each food, and possibly each company/ type (I think some people differentiate between different types of grapes).
Other hilchos brachos questions I forgot:
1. If you are planning to eat bread in the car, so you wash in your house, how should you do things? If you make homotzi in the car, it may be too long a distance between al netilas yadayiim and hamotzi, but you don’t have time to eat a kzayis in the house, so what should you do? (Note: this is not at all simple, I tried looking into it and discussed it with two Talmidei Chachamim, and I’m still not sure what the answer is).
2. Should women make a zimun? (granted it only needs asked once, but if you would make a list of all the questions that only need asked once, you would have a lot of them. And this is not the kind of thing that you can just look up, since even though the MB says it’s technically muttar, there are Poskim who say that it’s a problem nowadays. Also, I ended up asking more than once, because after I asked one Rav (who is not a Gadol) who said yes, I found out about a Gadol who said no, so I realized it’s a sheilah that needs asked to a Gadol. Furthermore, different people (people who are learned but not Gedolim) understand the MB differently in the first place).
3.Should women wash mayim acharonim?
