is it normal for a female friend of 7 years message my bf with hearts on snapchat?

my bf and I visited her place and when we were done dropping off some stuff, she messaged my bf on snapchat saying: thanks for coming 💗💗 with two heart emojis. my bf showed me the message. i guess ive never done that before with my guy friends because every guy friend would think I would want something more.

is this normal?

FYI, i also wrote the post called "my bf is crying that one of his female friends is leaving the state. is this a red flag?" pls be nice but truthful ♡
