As in the case of humans, those that come to drink here choose their drinking partners with care. Picking up a fight at a drinking hole may be part of innocent mischief or a serious affair best be avoided. One may be eaten in the process of slaking a thirst!
The anxious will dread these compulsory visits for drinking daily or every few days, not frequenting such places until it is absolutely necessary. So much worse in drought seasons when there are fewer places to choose from.
