You're a pro. Make it a BYOB event and provide plastic shot glasses if you wish. We have some small bottles of water and sometimes someone will bring a box of non spicy crackers like Ritz to share. You can get fancy and have history of the distillery or brand. We sometimes have raffles for $5 a shot on a nice $50 bottle. Any extra goes to the club. You can go simple or fancy but the bottom line is it's fun .I enjoy it.
