I sometimes take something to eat and drink with me to a punt. Wine, fruit, something like that.
Some punters might regard that as being soft and bringing a gift. I don't see it that way. They are for me to enjoy, as much as for the WG. Especially as I prefer a 1.5 to 2 hr session and some WG's don't offer any refreshment beyond a glass of water between rounds. Although, I'd like to think some WG's see it as a considerate gesture.
I usually end up leaving most of it behind when I leave. I am happy for them to have it, if they want it, and I can't be arsed carrying it away anyway. A lot of the time they do not seem interested in having any themselves while I'm there. I think sometimes they are suspicious that the food and drink could have been tampered with. I wouldn't be surprised if most of them just bin it immediately. Some may even offer it to their next punter to see if it has been drugged!
Occasionally, I've met playful WG's that like to get creative with the fruit. That's always memorable.
