I like drinking coffee in a paceline. Last time I did this, I took a big downhill slurp, pulling a lead on the group, then I took some quick sips in succession, thinking the others were still slurping, well I took a quick peek between slurps only to find a sipper on my wheel, panic then carnage as the last slurper not seeing the others sipping - crashed out. It was ok though as he was just slurping out of his cheap starbucks training cup, the rest of us had our handmade italian espresso cups, some with custom glazing.
Now I think it was the fault of the slurper, so I am never sipping with this group again - bunch a loosers!!!.
