Slow cranking that has been getting worse over weeks means the battery is already significantly degraded. Do not wait until Monday, a battery in that condition can fail completely overnight especially if temperatures drop or the car sits unused over the weekend.

Prices in Downtown tend to run slightly higher than Al Quoz or Deira simply because of the area overhead but the difference on a 50Ah Amaron is usually not dramatic, maybe 50 to 100 dirhams more at most. Worth it for the convenience if your time is tight.

Mobile service is your best option for Downtown honestly. Most reputable ones cover the area and can be at your office parking within 30 to 45 minutes during lunch hours without you needing to move the car anywhere.
