If you have more answers to add you can do that below.

Once you enter the lounge through the green armchair icon, look for the 3 icons at the center bottom. First one is speech bubble for the chat room; second icon is the teapot to enter the cafe; third is the calendar for the competition section. Select the teapot icon to enter the cafe. If someone has served you a drink in the last 30 minutes, a cup will be present to the right of the tips jar. Tap to drink and receive its energy and 5 tips will go to the player who served the drink. For you to receive tips, you must serve a drink. Tap on the teacup on the bottom right corner with the "+" sign. Select a drink from the window, see how much it will cost (first one free every 23 hours). Tap once more to agree to the cost and serve. When you serve a cup, you also drink it, get its energy and get 5 tips. Tips will remain above the jar uncollected and will only count toward the HW task when you tap the jar to collect your tips.
