About integrity

This happened two days ago but the incident is still making me think. 

It was 1:20 am. There was this balloon seller cycling home. He still had a few unsold balloons. 

For some reason, I parked. 

Me: भैया 1 गुब्बारा कितने का है? (Bhaiya, how much for a balloon?) 

He: दीदी आप पूरा bunch ले लो न। 100 के 5 हैं। (Didi, pls take the entire bunch. Its just 100 rs for 5) 

Me: ठीक है। दे दो। (OK. I will take the bunch) 

While putting the balloons inside the car, one balloon burst. 

He: दीदी, एक गुब्बारा फूट गया। (Didi, one balloon burst) 

Me: कोई बात नहीं। (No problem) 

He looked at his cart, which still had one bunch of 5 balloons unsold. Then he pulled out one balloon and gave it to me. 

He: ये लो। (Here, take this) 

Me (surprised): पर गुब्बारा तो मेरी गलती से फूटा है। (But that balloon burst because of my mistake!) 

कोई बात नहीं। आपने 5 गुब्बारे के पैसे दिए हैं।  (Doesn't matter. You paid for 5 balloons). 

In that moment, I learnt, once again, about integrity.
