Srevice Tax and sales tax charged in the single bill

There is a serious problem for me.
This is in my practical work. Ek Co. jiske hum Internal Auditor hai mein jo canteen hai us canteen ka jo monthly bill aata hai vo is trhan se hota hai.

1. Material Cost
2. Labour Charges (employed in canteen)
3. Service Charges
4. Vat on above all thee items
5. Service tax on all bill.

The problem is that is this posible that both the VAT and Service Tax are achrged in the same bill.VAT is related to Haryana. Before I chalange the bill I need yours help because canteen owner is also a very reputed firm in India.
Thanx in Advance
