Felt like I should have said something

Felt like I should have said something I was shopping today and met someone around my age M26 who also stuttered mildly. We discussed the clothing in the store and the energy was positive and funny. I noticed he stuttered, but didn’t mention anything about how I did too. I have been taking vitamin B1 (Thiamine) 500MG everyday and it’s helped my stutter. I now feel like I could have helped him with his. But I didn’t want to offend him, just in case. Just getting this off my chest. Would you have said something? Anyway, thanks for reading. And Thiamine really seems to have helped me for anyone who is interested in trying it.
