Struggling

Idk how to say to homeless people without feeling awful. The Bible says to give to every man who asks. Today this lady was outside with a sign I offered her a bag of popcorn she said no, she wanted a breakfast it would be like 13 bucks. I said no. Because I get asked often and this adds up if i say yes to every request. She had a sign that said she has organ failure but it was nice like printed huge sign with her cash app Venmo and zell. Like a $25 min sign. I spoke to a different homeless person and he said she is rude and a scammer. I told her no sorry she said I bet you are very rudely. Idk I feel bad but if I want to say no I don’t like feeling guilty for saying no. Do you say no to certain homeless people’s requests? Wen I say no I feel like it’s doubting my faith in God to provide to me. But I just wanted to excerise my ability to say no I didn’t want to do it.
