Charging VAT & Service Tax together

Dear Friends,

Recently I had lunch at a reputed resturant in Hyderabad and to my surprise they have applied VAT & S. Charge together. Below is the details.

Buffet Lunch: 438.00

VAT @ 14.5%: 69.86

S.C. @ 10%: 43.80

Total: 552.00

I want to know whether any entity is allowed to charge VAT & Servcie Charge together and whether they are permitted to charge the VAT more than 4%?

Thank you,
