Welcome to the forum!
My mother is elderly, and each Sunday she brings a small cloth bag with her. In it she has her meds, hanky, bottle of water, etc.
She's a diabetic, etc....but, refuses to eat/drink Sundays because she always tries to go to Holy Communion.
However, if she feels ill, she has that bottle of water...
To draw less attention to it though, she sticks a drinking straw in it. Therefore, she quietly sips the water, nobody sees her lifting it, nor does the plastic crunch or make any noise.
Just a thought. People can't complain, about something they don't "see".
However, mostly do not get discouraged. There are always folks who try to "correct" every little thing they think is a mistake.
...but, that's not just a church occurrence...that happens everywhere.
