I have a modified gaming chair that has foldout platforms for the HOTAS and a mouse pad (not shown).
But for drinking and using a controller I hang them around my neck
And the headset sits over the chair headrest when not in use 
Another option is a drink holder for a bicycle hanging off one side (for long necked beer bottles).
First world problem indeed
