TENPIN BOWLING RIP-OFF!! PLEASE EXPLAIN??!!

I have just queried with the Supervisor at the Tenpin Bowling the cost for 26 people to play tenpin as a Teambuilding event and get quoted R100 per game??!!! Yet if I go there as an individual I pay R50 per game? If anything, there should be a discount for group bookings but it gets doubled??!! We have had Teambuilding events at Tenpin at Northcliff and Brigh****er Commons and have never paid those ********** costs?? Please can someone give me a call and explain why the ********** and exhorbitant cost for a Group booking? We were wanting to play 2 games which SHOULD be R100 for 2 games so this establishment would rather lose R2600??!!! I just don't understand the thinking so would really appreciate a call as a matter of urgency to explain. Thank you.
