It depends
If they're running around like coked up spaniels due to under-staffing (as the staff at the local 'spoons always seem to be) then management might (particularly if not real ale drinkers like the guy who tried to argue that the malt vinegar taste in my mate's pint was "normal for a real ale, they tend to be punchy") be inclined to skip, or not be as through as they should be with, that part.

That said caustic soda probably would do you sufficiently bad damage to be a worry from a litigation stand point...
