First of all, I don’t know about the store you work in, but hearing someone say “store” sounds bummy. Unless it’s sefarim or suit store…most of the stores where I live are manned by bums, not the type of people looking for a marriage. Definitely not wearing black and white.
Let’s say he is a great guy, works in a store, wears black and white, learns every morning or evening, works in a good environment, has a rav, and a million other things I check out for everyone, than why not?
My question is if he is planning on making parnassah for 7-15 people, he needs a better job later on. So…why shouldn’t he spend the time now, when he is single and doesn’t desperately need the money to focus on excpanding his abilities and talents, so he could make more money in the future.
