No problem with leaks if the reservoir bottle and master cylinder caps are sealed properly. Biggest problem is when the jam jar or similar gets knocked over when the bleed nipple is tightened and the bleed tube gives it a nudge!
Ey up Old Un.....I might knock a jam jar full of manky brake fluid over, but never a glass full or otherwise of alcoholic content !! The only place that gets spilt is down me throat.
