Caller: [Dials restaurant]

Voicebot: "Thank you for calling Bella Italia. 
I can help you with reservations, hours, 
and menu information. How can I help you?"

Caller: "I'd like to book a table for 
        Saturday night."

Voicebot: "I'd be happy to help with a Saturday 
reservation. How many people will be dining?"

Caller: "Four people"

Voicebot: "Perfect, a table for 4 on Saturday.
What time would you prefer?

We have availability at:
• 18:00
• 18:30
• 20:30
• 21:00

Note: Our 19:00-20:00 slots are currently 
full, but I can add you to the waitlist."

Caller: "20:30 works great"

Voicebot: "Excellent! I have a table for 4 at 
20:30 on Saturday, January 18th.

May I have your name for the reservation?"

Caller: "Maria Johnson"

Voicebot: "Thank you, Maria. And a phone number 
in case we need to reach you?"

Caller: "555-123-4567"

Voicebot: "Perfect! Let me confirm:

📅 Saturday, January 18th at 20:30
👥 Table for 4
👤 Name: Maria Johnson
📱 Contact: 555-123-4567

Any special requests-highchair, 
dietary restrictions, special occasion?"

Caller: "Actually, it's my husband's birthday"

Voicebot: "How wonderful! I've noted that it's 
a birthday celebration. We'll make sure 
the evening is special.

Would you like us to bring a complimentary 
dessert with a candle?"

Caller: "That would be great, thank you!"

Voicebot: "My pleasure! You'll receive a 
confirmation text shortly. We ask that you 
arrive 10 minutes before your reservation 
time. If your plans change, please call 
us at least 4 hours in advance.

Is there anything else I can help with?"

Caller: "No, that's all. Thanks!"

Voicebot: "Thank you for choosing Bella Italia. 
We look forward to celebrating with you 
on Saturday. Goodbye!"

Caller: "Table for 6 tonight at 7 PM?"

Voicebot: "Let me check availability for 6 guests 
at 19:00 tonight...

I'm sorry, we're fully booked at 19:00. 
However, I do have some alternatives:

Option 1: Tonight at 17:30 (early dinner)
Option 2: Tonight at 21:15 (late seating)
Option 3: Tomorrow at 19:00 (same time)

I can also add you to tonight's waitlist at 
19:00-if a cancellation comes in, we'll 
call you immediately.

Which would you prefer?"

Caller: "Put us on the waitlist, 
        and book 21:15 as backup"

Voicebot: "Smart choice! I've done both:

✅ Waitlist: Tonight 19:00 for 6 guests
   (We'll call 555-123-4567 if a spot opens)

✅ Confirmed: Tonight 21:15 for 6 guests

If we can seat you at 19:00, I'll automatically 
cancel the 21:15 booking. Otherwise, we'll 
see you at 21:15.

May I have a name for the reservations?"

Caller: "Hi, I have some questions before booking"

Voicebot: "Of course! I'm happy to help with any 
questions about our restaurant."

Caller: "Do you have gluten-free options? 
        My wife has celiac disease."

Voicebot: "Absolutely! We take allergies very 
seriously. For celiac disease:

Gluten-free options available:
├── Dedicated gluten-free pasta
├── Risotto dishes (naturally GF)
├── Grilled fish and meat entrées
├── Most appetizers can be modified
└── Gluten-free dessert options

Our kitchen has separate prep areas for 
allergen-sensitive dishes, and our staff 
is trained in cross-contamination prevention.

I'd recommend mentioning the celiac requirement 
when you book, so the kitchen is prepared.

Would you like to make a reservation now?"

Caller: "Yes, what's available Friday night?"
