I do recall sitting right next to the anchor for this climb...which is also the anchor for sface, mf and nose...
all on jello tower...not below feet...
and as dru says if the climb is multipitch and the anchor is below a ledge between pitches then the sportmonkey who drilled the bolts is an idiot...
however, if the bolts are below a ledge and you want to belay on the nice comfy ledge, do as mattp suggests and brace your feet. likewise, keep the belay nice and snug for the second. this should virtually eliminate any chance from being "yanked off" (if the second falls).
when in doubt back it up with pro.
