Oh btw you are probably recieving offerings all the time, you just haven't noticed. Or maybe you have, you're clever.
Someone sharing their food with you? Offering.
Free snacks up for grabs in the breakroom? Offering.
A well-timed joke, kindness, or compliment? Offering.
Friend hands you a pretty rock or flower? Offering.
Gratuities for a job well-done, especially when given sneakily and evasive of no tipping rules? Most definitely an offering. (Shoutout to that one customer, the cough drop you gave me I ended up needing later that day. It was my favourite flavour too. May your shoes stay dry in the heaviest of rain and snow.)
