There's a pattern. Like social media influencers on IG, the main tactic SWs employ is to strategically posing with "gifts" they have received with the hopes of creating the desire in their suitors to 1up the next bloke, and/ or to impress their peers. But, for many, the "gifts" are temporary purchases, loaners from their friends, or window shopping captures.
We all know that in social media land, perception matters more than reality.
By all means, tip/ treat those you want to be supportive of, but don't feel obligated/ pressured because of what you read or see on social media - likely 97% of it all is contrived.
