Can i contract hsv1 from eating a macaron right after someone with it? touching a straw they sipped right after with my hand?

It's possible: Oral herpes is passed along from person to person via infected saliva. The amount of saliva required is small. The herpes virus is microscopic and can be passed along through simple means such as kissing, sharing silverware or lipstick, or drinking after someone else. It can also be spread through oral sex. As you can see, it's fairly easy to transmit; almost as easy as getting a common cold.

Wimpy Virus: It is important to remember that viruses like hepc, HIV and others are strings of proteins that are connected by very weak bonds. They require many things to stay active and need living cells to reproduce and survive. Unless there was infected gross blood, mucous or some other organic substance on the macaroni or straw and it got immediately into your body, the odds are almost zero.
