Be sure to rinse the bottle or can out at least once before you fill it with the water you intend to drink, to get rid of any residual alcohol in the bottle or can.
Put your mouth to the drink occasionally without actually drinking any so it doesn’t look suspicious that your drink is disappearing on its own. Tell a friend (or several), “Mmm, this is good, try this!” and have them take a sip so your drink disappears faster.
If you can’t get away with pouring the shot out, take it but don’t swallow it. Reach for a soda bottle (preferably your own personal one) and pretend to drink from it as a chaser, backwashing the alcohol from your mouth instead. [5] X Research source
