I thought it was really silly when I seen that they came out with a Bar Box line of cues.
Most pool halls in recent years have mostly, or at least 50% 7 foot bar tables.
I understand, in the old days, most pool halls probably had all regulation size 9 foot tables, but ever since the bar leagues got really popular, some pool halls may have switched out their 9 foot tables for 7 foot tables.
I "regulation size" pool table only means that it is twice as long as it is wide. 7', 8', 9' & 10' tables can all be "regulation tables".
