Clearly... And here we are with your story of how some chick blasted your phone number on IG because you made her feel trapped while holding up a long line of people all who have every right to not be inconvenienced by your shit in their own right. Clearly your sense of iudgement is not in need of calibrating, keep on keeping on.
Show all the interest and read your IOI's. No issues there. Maybe read the rest of the setting though is what I'm saying... A long line full of people is not it.
Let it be a lesson learned. Don't be an ass and pressure someone who can't leave their post/avoid the conversation... ESPECIALLY with a huge fucking line. Now you're just being a double douche.
