Is this a good strategy to make friends at college parties or clubs, especially girls?

Why I should tell people about my intentions towards them:

Now, this will probably make them understand what my intentions are. I’m also not trying to hook up with them at all, but if I simply tell them that “I’m just looking to be friends”, then they shouldn’t be too judgmental/shallow towards me?

My past mistakes involved me just asking them for their Snapchat or number without telling them my intentions in the initial question, only after when I received their contacts.

On an extra note, getting a girls number or Snapchat doesn’t mean that I’m interested in dating her. People exchange contact info all the time. Overall, it’ll either lead to a relationship or friendship, depending on both of their intention & interest levels.

Well, I guess it worked because I tried it out and nothing bad happened…
